Acetalization of hydroxy- benzaldehydes, which has been reported to be unsatisfactory under normal protonic acid condition, and of acetophenones, has been efficiently carried out in benzene solution using [Ru(CH₃CN)₃(triphos)](OTf)₂ (triphos = CH₃C(CH₂PPh₂)₃) as a catalyst and removing the water by azeotropic distillation.
