A number of unusual transformations were observed when di-t-butyl and diphenylsulfur diimide were treated with t-butylcyano- and chlorocyanoketene. These include the fomation of reactive thione-s-imines, which subsequently lead to 3-isothiazolidinones and benzisothiazoles. Other products include a cyclic thioimidate and a β-lactam.
