摘要

The first dialkyl-substituted silicon-chalcogen doubly bonded compounds [R2Si X; R2= 1, 1, 4, 4-tetrakis (trimethylsilyl) butane-1, 4-diyl, X= S (4), Se (5), and Te (6)] were synthesized by the reactions of an isolable dialkylsilylene R2Si:(3) with phosphine sulfide, elemental selenium, and elemental tellurium, respectively. Systematic changes of characteristics of silicon-chalcogen double bonds are elucidated by X-ray analysis, UV-vis spectroscopy, ...
