We found an easy method for conducting the Ph3P=C(X)H -> -> Ph3P=C(X)C(S)NH2 transformation that is based on treating accessible phosphonium ylides first with acetyl isothiocyanate and then with sodium hydroxide.New thiocarbamoyl-containing reagents readily enter into cyclocondensation with α-halocarbonyl compounds and chloroacetonitrile; this property was used for synthesizing a number of stabilized ylides of the general formula Ph3P=C(X)Ht.
