Stable Multiply-Bonded Organosilicon Compounds

摘要

From this brief survey, it is apparent that multiply bonded silicon compoundsprovide an active new area of chemistry. Both the multiply-bonded compounds themselves, -and the compounds produced from them in chemical reactions, provide new structures Of great interest. There is firm evidence from matrix isolation or trapping studies for R2Si=O, RSi equivalent N, RN equivalent Si, RN=Si=NR, R2Si=C=CR'2, silabenzene and 1,4-disilabenzene, although no stable compounds with these structures have yet been isolated. Still other unknown multiply-bonded compounds can be imagined, and are likely to provide synthetic challenges in the future.
