Abstract

Solutions of reactive intermediates of structure I (carbodiimides, isocyanates, and isothiocyanates) which may be used for subsequent reaction without further treatment may be prepared conveniently by treating compounds of structure I1 with solutions of silver nitrate or mercuric chloride. An alkyl mercaptan is eliminated in the reaction as an insoluble metal mercaptide. In typical experiments, products of condensation of the intermediates ...
