Chemical Reactions and Properties of Organosilicon Compounds to New Materials
Abstract
Polysilane High Polymers and Oligomers. a) Light-scattering studies of molecular weight and chain conformations were carried out for six polysilane samples. b) Silicon-29 NMR spectroscopy was employed to study configurations of polysilane polymers and oligomers. c) A new class of substances, poly(disilanylene-co-ethynylene) copolymers, were synthesized which show properties indicating sigma - pi electron conjugation. Divalent and Multiply- Bonded Silicon Compounds. a) Complexes of silylenes, R2Si:, with various Lewis bases have been observed spectroscopically. b) Reactions of disilenes (R2Si=SiR2) with nitro compounds, nitroso compounds, azides and oxygen have been studied, leading to previously unknown types of cyclic silicon compounds. c) A new, very stable disilene, 1,2-dimesity1-1,2-bis(1-adamantyl)disilene, was synthesized and investigated. d) The first silandiimines, RN=Si=NR, have been made and observed at low temperatures. e) Stable silanamidines, RNH=Si(X)=NR, and silanamidine anions, RN Si(X) NR-, have been synthesized and studied. Organic silicon compounds.
