Abstract

Abstract The reaction of some arylnitrile oxides with potassium thiocyanate in acetone at ambient temperature, has been investigated. Those having para-or meta-halo (or nitro) substituents give 3-aryl-5-imino-Δ 2-1, 4, 2-oxathiazolines as stable cycloadducts. ortho- Substitutionn, on the other hand, led directly to the corresponding 5-(carbamido) imino analogues. The structures of these new heterocycles are supported by elemental ...
