资源简介：
Reactions of silylenes with organic substrates generally lead to silicon(IV) compounds. Ligand substitution at the silicon(II) atom of silylene, without changing the formal +2 oxidation state, is very rare. We report herein a straightforward route to functionalized silylenes LSiX (L = PhC(NtBu)2 and X = PPh2 (1), NPh2 (2), NCy2(3), NiPr2 (4), NMe2 (5), N(SiMe3)2 (6), OtBu (7)). Silylenes 1–7 have been prepared in quantitative yield by a modified ligand exchange reaction of PhC(NtBu)2SiCl (LSiCl) with the corresponding lithium or potassium salts. Compounds 1–7 were characterized by spectroscopic and spectrometric techniques. Single-crystal X-ray structures of 1, 3, and 4 were determined.
