## Abstract The reaction of phenyl isothiocyanate with the active methylene reagents 1aβe gives the nonisolable 1:1 adducts 2aβe. The latter react with Ξ±βhalogenated compounds, e.g. phenacyl bromide, bromoacetyl bromide, chloroacetone, chloroacetonitrile and some hydrazonoyl halides to give the cor
