Since the beginning of the seventies, organophosphorus chemistry has been completely rejuvenated by the discovery of stable derivatives in which phosphorus has the coordination numbers one or two. The chemistry of these compounds mimics the chemistry of their all-carbon analogues. In this Review article this analogy is discussed for the phosphorus counterparts of alkenes, alkynes, and carbenes. In each case, the synthesis, reactivity, and coordination modes are briefly examined. Some special electronic configurations are also discussed, which include one-electron Pbond;P bonds, strained bonds, and aromatic systems. To conclude, some potential applications of this chemistry in the areas of molecular materials and homogeneous catalysis are presented. 相似文献

In recent years, research in organophosphorus chemistry has mainly focused in designing newer and better phosphorus ligands for synthesizing novel metal complexes with improved catalytic activities. Aminophosphines [tricoordinate phosphorus(III)–nitrogen systems] are considered as versatile compounds owing to the presence of nitrogen centres which, in principle, can influence additional reactivity features. They are quite sensitive to air and moisture due to the presence of polar P? N bond(s). In spite of this, research in aminophosphine chemistry is gaining momentum day‐by‐day and this is due mainly to one reason: their rich behaviour as ligands in metal complex chemistry and subsequently in catalysis. Their role as synthons in inorganic heterocyclic chemistry has also helped produce new types of heterocycles. In this paper, the chemistry of simple acyclic aminophosphines (synthesis, characterization, reactivity and applications) is covered and particular focus is given to their ability to form chalcogenides along with their role played as ligands in coordination chemistry and as synthons in inorganic heterocyclic chemistry.

240 Years have passed since the discovery of elemental phosphorus. During that time organophosphorus chemistry has emerged as an interesting and exciting field of research. Recently organophosphorus chemistry has been raised to a new level. Organophosphorus compounds have found applications in asymmetric organocatalysis for the synthesis of optically active compounds of synthetic or biological importance. The aim of this review article is to present recent contributions to this developing field of chemistry and to point out synthetic advantages of methodologies developed so far. 相似文献

Abstract Although there has been considerable interest in the chemistry and metal complexation of low coordinate phosphines, there are very few examples of bisphosphine systems where both phosphorus atoms are trivalent and only one of the centers is two-coordinate1,2. An example of such a system is the 4-phosphino-2,5-dimethyl-1,2,3-diazaphosphole obtained from acetone methylhydrazone and phosphorus trichloride3. This bisphosphine contains a two-coordinate endocyclic phosphorus and a three-coordinate exo phosphorus center. The exo phosphorus preferentially coordinates to metals but under certain conditions the two-coordinate phosphorus will also coordinate4. 相似文献

In recent years both acyclic and cyclic sulfur ylides have proved to be interesting and versatile ligands in preparative organometallic chemistry. In addition to paralleling the coordination chemistry of their phosphorus analogues, sulfur ylide complexes show specific structural and chemical features; they are becoming more important in preparative inorganic and organic chemistry, and may also be biochemically relevant as methylene transfer agents. Recent studies of the complexes of the ylidic λ4-thiabenzenes and λ6-thiabenzene 1-oxides have frequently demonstrated unexpected and novel reactions, and thereby enriched the chemistry both of ylides and of carbonylmetals. 相似文献

Dramatic developments have taken place over the last few years in the chemistry of complexes containing Zr-P bonds and their utilization in organophosphorus chemistry. This review discusses the synthesis and reactivity of compounds containing Zr-P single and double bonds, phosphazirconacycles, and Zr complexes of substituent-free phosphorus. Applications in both stoichiometric and catalytic syntheses provide access to a variety of novel organophosphorus compounds and illustrate the potential of the organometallic approach to the synthesis of main group compounds. 相似文献

Versatile alkylation reactions give access to symmetric, homoleptic nonsymmetric, and heteroleptic symmetric hexaalkylated 1,2-diphosphonium derivatives as bottleable salts in high yields. A series of 1,2-diphosphonium salts has been isolated and characterized, representing prototypical phosphorus analogues of ethane. Additionally, the solid-state structures for four derivatives have been determined crystallographically. Nonsymmetrically substituted derivatives of 1,2-diphosphonium cations enable the direct observation of 1J(PAPB) coupling constants for two tetracoordinate phosphorus centers. The synthetic approaches promise access to a vast array of derivatives and will provide means to the systematic development of phosphorus analogues of hydrocarbon chemistry. 相似文献

Abstract lmines are important classes of compounds in chemistry. In our continued investigation in the studies of the interactions betwcen group 4 (Zr, Ti) elements and main group elements we recently developped a new methodology for the preparation of various σ3, λ3 phospha-imines. Extension of this work allowed us to prepare unprecedented 8-π electron 6-membered phosphorus heterocycles; 1, 4 σ3, λ3 diphospha-2,6-diazines. The formation of these diazines involved for the first time the use of phosphorus derivatives as cyclization promoted reagents in zirconocene chemistry. 相似文献

In contrast to the numerous known and often technically important mono- and diphosphorus compounds with phosphorus in its maximum oxidation state, polyphosphorus compounds led only a shadowy existence up to about twenty years ago. One of the reasons for this was the properties of such compounds, which made their handling and structural characterization difficult. This problem was solved by the development of modern preparative techniques and, especially, by the further methodological development of nuclear magnetic resonance spectroscopy. Thus, a fascinating new branch of phosphorus chemistry has been opened up in recent years. The first comprehensive review on this subject was published five years ago. Since then, research on this “element-near” chemistry of phosphorus has produced further impressive advances with the result that a surprisingly large variety of compounds with skeletons consisting of chains or rings of phosphorus atoms is known today. However, the recent observation of the spontaneous formation of the “aromatic” pentaphosphacyclopentadienide ion, P, during the synthesis of phosphorus-richer polyphosphides from phosphorus-poorer compounds in solution and the discovery of the inversion of phosphorus in tetra- and pentacyclic organophosphanes demonstrate that this field is still capable of producing surprises. 相似文献

The large number of known stable compounds in which phosphorus has a low coordination number makes it clear that such compounds can no longer be regarded as “exotic” in main group chemistry. While the rich chemistry of P? C multiply bonded systems makes clear their affinity to their organic congeners, iminophosphanes in particular are also of increasing importance. The linkage of a phosphinidine fragment with an imine fragment via a multiple bond gives rise to a class of compounds with an unusually wide range of structural types. This in turn leads to a broad spectrum of chemical behavior which makes iminophosphanes extremely useful synthetic building blocks in organoelement chemistry. 相似文献
