Article abstract of DOI:10.1016/S0040-4039(01)90027-9

A mild and convenient method for ring expansion of 1,3-dithiolans and 1,3-dithians to dihydro-1,4-dithiins and dihydro-1,4-dithiepins, respectively, using phenyl selenenyl chloride in methylene chloride is described.A mechanism involving sulphenyl chloride derivatives as intermediates is proposed.
