The rhodium(II) acetate-catalyzed reaction of various α-diazocarbonyl compounds with alkyl, phenyl, and benzoyl isothiocyanates gave 2-imino-1,3-oxathioles in good yields. 2(3H)-Oxazolethione was obtained as a byproduct only in the reaction of diazodimedo

A facile synthesis of N-acyl-1,3-oxathiol-2-imines, 7, is reported.It comprises the reaction of O-alkyl acylcarbamothioates, 4, with 2-chloroketones in the presence of alcoholic sodium alkoxide.The resulting O-alkyl-S-substituted-N-acylcarbonimidothiates, 6, undergo cyclization with elimination of alcohol, spontaneously, or upon heating in boiling toluene to form 7.
