摘要：
An efficient and rapid procedure for the preparation of sulfonylsemicarbazide from Sulfonylhydrazides and triphosgene in one-pot sequence is described. In the two-steps sequence: sulfonylhydrazides and acetylsulfanilylhydrazide were transformed into the corresponding intermediates using triphosgene in 1,4-dioxan/water or tetrahydrofuran medium and then the intermediates were converted in situ into sulfonylsemicarbazide in high yields and shorter times related to previous methods.
