Acyl ylides and hexamethyldisiloxane are produced in the one‐pot reaction of free carboxylic acids with bis(trimethylsilyl)methylenetriphenylphosphorane [Eq. (a)]. Dicarboxylic acids and amino acids also undergo this reaction; only O ‐protected tartaric acids and monomethyl tartrates yield undefined elimination products.
