In the presence of a catalytic amount of trityl perchlorate, trimethylsilylcyanide reacts with the dimethyl acetals of chalcone derivatives, with simultaneous double bond isomerization, to yield γ-methoxy-α,β-unsaturated carbonitriles. Trimethylsilyl sulfides react with dimethyl acetals derived from α,β-unsaturated ketones to yield 1,3-bis(alkylthio)propene derivatives under similar conditions.
