Unusual reactivity of N-acyl imides: N-aroyl-1,2,4-dithiazolidine-3,5-diones as acyl isocyanate equivalents†
Abstract
Crystalline samples of three N-aroyl-1,2,4-dithiazolidine-3,5-diones have been prepared as the first examples of a novel class of compound that displays the reactivity of an acyl isocyanate when treated with nucleophiles.
