Abstract By means of NMR and IR spectroscopy there has been established that the equilibrium position in the phosphoryl-hydroxyylide prototropic systems /I-V/ depends on the nature of substituents at the phosphorus atom. 相似文献

Abstract Direction of alkylation of phosphoranes (I) depends on the nature of the substituent Y and the alkylating agent. Unsubstituted phosphorane reacts with CH3J yielding only the product of C-methylation (II), whereas the reaction with Me2SO4 proceeds at both ends of the OPC-triad, preferably yielding the O-alkylation product (IIIa, 80%). 相似文献

2-Oxo-1,2-azaphospholanes and 1,2-azaphospholanium salts containing an amino acid fragment were synthesized by intramolecular
P-alkylation of N-3-chloropropyl-substituted tricoordinate phosphorus amides. Hydrolysis of 2-oxo-1,2-azaphospholanes at the P-N bond gives
rise to γ-aminopropylphosphonic acid derivatives.

A reaction of N-allyl-substituted aminomethylene-1,1-bisphosphonates with aromatic nitrile N-oxides was used to obtain new aminomethylenebisphosphonates with one or two 3-arylisoxazoline rings at the nitrogen atom. NMR spectroscopy studies showed that the bisphosphonates with two isoxazoline fragments in the molecule exist in solution as a mixture of two diastereomers. 相似文献

PPh2. The solid complexes isolated from pyridine restore dimeric structure A. According to the data of X-ray diffraction analysis,
the 1:2 complex isolated from pyridine has the structure [S=P(Ph2)(CH2)2(Ph2)P−(NO3)Ag(Py)−P(Ph2) (CH2)2(Ph2)P=S]Py. According to the data of IR spectroscopy, dissolution of this complex in chloroform leads to the formation of the
dimeric structure Ag2Ph2P(S)(CH2)2PPh2]4(NO3)2.
