✦ Synopsis


A facile homologation procedure for the conversion of carbonyl compounds into ketene-O,S-acetals is described. These intermediates are readily converted into ketene-O-silyl,S-acetals, thioesters, and carboxamides.

The title reagent (I) methylates a variety of mono-and diketones such as (II), (IV), (VII), or (IX). Aromatic aldehydes (XI) and (XIII) undergo simple methylation only after activation with AlCl3. Reaction of (I) with terminal acetylenes (XVI) allows the carbonyl-alkynylation of diphenyl ketone (IIa
