A new three-component reaction of N-chlorourea, olefins and acetonitrile is reported. Styrene gives N-(1-ureidoethylidene)-2-choro-1-phenylethylamine, N-(2-chloro-1-phenylethyl)acetamide and 4-phenyl-2-oxazolidone. Addition proceeds in a Markovnikov manner as shown by structural evidence. Cyclohexene gives N-(1-ureiodoethylidene)-2-chlorocyclohexylamine and N-(2-chlorocyclohexyl)acetamide. The stereochemistry
A Lewis base catalyzed chloroamidation of olefinic substrates was achieved using diphenyl selenide as the catalyst. The reaction conditions are mild and suitable for a wide range of substrates including those which are acid labile.
