Directly generated potassium enolates of aldehydes react with diphenyldisulfide to give the α-sulfenylated aldehydes. Reaction with iodine likewise provides the α-iodo aldehydes.
Addition of methoxy(phenylthio)methyllithium to ketones, followed by rearrangement of the adducts, provides a new method for the preparation of α-(phenylthio)aldehydes. The rearrangement is stereospecific.
