Conclusions
199Hg chemical shifts indicate that in dibenzyl derivatives of mercury and in benzylmercury bromides, there is, conjugation of the C-Hg bond with the orbitals of the aromatic ring, and also intramolecular coordination of the Hg atom with the Br atoms located in the o-position relative to the CH2HgBr group, leading to the formation of a five-membered chelate ring. Such coordination interaction does not have an appreciable effect on the13C chemical shifts or the JC-Hg constants.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 793–799, April, 1985. 相似文献

An unusual reaction of diaminogermylene and diaminostannylene with sterically hindered phenols which leads to the formation of stable phenoxyl radicals in high concentrations was found. The reaction mechanism was proposed. Amides [(Me3Si)2N]2E (E = Ge, Sn) were investigated electrochemically. 相似文献

Optimal conditions have been developed for the synthesis and isolation of phenoxy- and benzyloxypropynyl alcohols of the tetrahydropyran and tetrahydrothiopyran series. The structures of individual isomers have been established on the basis of the 1H and 13C NMR spectra. The stereochemical results of the reaction depend on the initial ketone structure. 相似文献

The behavior of binuclear “ladder” type complexes FpL, where Fp=Cp(CO)2Fe, L=p-MeC6H4Cr(CO)3 (4), CH2C6H5Cr(CO)3 (5), andp-FpC6H4Cr(CO)3 (6), under conditions of metallation was studied. Unlike compounds5 and6, the σ-bound ligand L in compound4 migrates from the iron atom to the cyclopentadienyl ring to give complexes Me(CO)2FeC5H4−C6H4(p-Me)Cr(CO)3. The electrochemical reduction potentials of the complexes4–6 and the rearrangement products were measured. The migration activity of L is determined by the ease of reductive cleavage
of the Fe−L bond and the susceptibility of the system to undergo intramolecular electron transfer from the Cp ligand to the
aromatic ring.

Phenoxy-and benzyloxypropynyl alcohols of the phosphinane series are synthesized. The steric structure of individual isomers
is established by means of 1H and 13C NMR spectroscopy. Stereodirection of the ethynylation of trans- and cis-2,5-dimethyl-1-phenyl-2-thioxo-λ5-phosphinane-4-ones is studied. 相似文献

The acid hydrolysis of 9,14-bis(2-methoxycarbonylethyl)-11-12-benzo-3,4-(4,5-dimethylbenzo)-10,13-dioxo-1,6-dithia-9,14-diazacyclohexadeca-3,11-diene leads to the corresponding 9,14-biscarboxy derivative. The reaction of 4,9,15,20-tetrakis-(2-methoxycarbonylethyl)-6,7,17,18-dibenzo-5,8,16,19-tetraoxo-1,12-dithia-4,9,15,20-tetraazacyclodocosa-6,17-diene with hydrazine hydrate and subsequent treatment with NaNO2 gave the corresponding tetraazide. The reaction of this tetraazide with histamine and histidine leads to macroheterocycles, containing exocyclic histamine and histidine fragments.For Communication 6, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 130–133, January, 1993. 相似文献

The potentials of electrochemical oxidation (
) and reduction (
) of monobromo- and isomeric di- and tribromo[2.2]paracyclophanes as well as
of mono-, di-, and tribromobenzenes were measured in acetonitrile. The similarity between the properties ofpseudo-para-disubstituted cyclophanes andmeta-disubstituted benzenes, on the one hand, andpseudo-meta-disubstituted cyclophanes andpara-disubstituted benzenes, on the other hand, was confirmed by the existence of a linear relationship between
of bromo-substituted [2.2]paracyclophanes and
of the corresponding bromo-substituted benzenes. The results were explained in terms of the qualitative theory of molecular orbitals, taking into account a through space interaction between the -systems of the benzene rings.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 5, pp. 839–845, May, 1994.The authors wish to express their gratitude to Professor R. Hoffmann (Cornell University, USA) for a useful discussion and criticisms of the text of this paper.This work was financially supported by the Russian Foundation for Basic Research (Project 93-03-5246). 相似文献

Electrochemical properties of tetra(3,5-di-tert-butyl-4-hydroxyphenyl)dodecachlorophthalocyanine complexes of cobalt(II) and lutetium(III) in DMF solutions have been studied.
It was suggested that in the presence ofn-butyl bromide, the electrochemically generated monoanionic complexes undergo alkylation at the metal atom. The geometries
of the neutral and anionic complexes were calculated by the ZINDO/I semiempirical method.
