摘要

Abstract Treatment of amino sulfines (thioamide S-oxides) 1 with triethyloxonium tetrafluoroborate, followed by sodium carbonate, leads to α-imino sulfenates 3. Reaction of 3 with primary and secondary amines gives α-imino sulfenamides 5. Treatment of amino sulfines with sodium hydride, followed by an alkyl halide, leads to the formation of α-imino sulfoxides 6, which are extremely sensitive towards hydrolysis. With ketenes, the imines 6 ...
