Acylsilanes can be synthesized by treating acyl anion equivalents with silyl halides (typically
trimethylsilyl chloride, tmsCl). Silylation of 2-lithio-
1,3-dithiane, followed by hydrolysis of the dithioacetal group with
mercury(II) chloride. Analogous methods has also been used to produce acylgermanes. Several approaches to acylsilanes start with carboxylic acid derivatives. ==Reactions==
