Heterocycles from nitrile oxides. I. 5‐imino‐Δ2 ‐1,4,2‐oxathiazolines

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‐Δ2‐1,4,2‐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 analyses and spectral data.
