N,N′-Bis(methoxycarbonyl)sulfur diimide (29) has been used frequently in organic synthesis (see Section 40.11.6.2). This reagent has been prepared by treatment of methyl N,N-dichlorocarbamate (28)[17,62] with sulfur dichloride in the presence of pyridine (Scheme 15).[16] More recently, it has been prepared by disproportionation of methyl N-sulfinylcarbamate in the presence of pyridine.[18]
