1,3-Thiazole-5(4H)-thione oxides 2 were prepared by oxidation of the corresponding 1,3-thiazole-5(4H)-thiones 1 with m-chloroperbenzoic acid (Table 1). Addition reactions of 2 with organolithium and Grignard reagents yielded 4,5-dihydro-4,4-dimethyl-1,3-thiazol-5-yl methyl sulfoxides of type 4via thiophilic attack (Table 2). Whereas the reaction with the organolithium compounds proceeded with fair-to-excellent
