A new method for the ring expansion of 1,3-dithiolanes and 1,3-dithianes to dihydro-1,4-dithiins and dihydro-1,4-dithiepines, respectively, using tert-butyl hypochlorite at room temperature is described. The salient features of the protocol include mild reaction conditions, very short reaction time, and high yield.
