The reactions of aryl acetals/ketals and triphenylphosphine hydrobromide gave the corresponding aldehydes/ketones and alkyl phosphonium bromides. This reaction was applied to convert acetals/ketals to the corresponding aldehydes/ketones under an anhydrous and convenient condition (50 oC, 5 min, up to 90% yield), and acid sensitive functional groups were compatible.
