An efficient and widely applicable reagent-free method for the synthesis of alkyl and arylisocyanides has been established. The electrochemical reduction of alkyl and aryl carbonimidoyl dichlorides under constant cathode potential leads to the corresponding isocyanides in almost quantitative yields. The availability of the starting materials, the mildness of the reaction conditions as well as the

Electrochemical reductions of monothiobenzils in the presence of either aroyl or carbonimidoyl dichlorides were carried out, yielding products with sulfur retention. Electrolyses in the presence of aroyl chlorides led to previously unknown (Z)-α-aroyloxy-β-aroylthiostilbenes in high to quantitative yields, whereas reactions in the presence of arylcarbonimidoyl dichlorides provided novel 4,5-diaryl-2-arylimino-1

The Synthesis and 1,4-Addition Type Ring-opening Polymerization of<i>N</i>-Substituted Cyclic Iminocarbonates
of N-substituted cyclic iminocarbonates have been studied. N-Alkyl and N-aryl cyclic iminocarbonates have been prepared by the reaction of sodium ethylene glycorate with the corresponding imidophosgenes. N-Halogeno cyclic iminocarbonates have been prepared from glycols, potassium cyanide and halogenes. The ring-opening polymerization of the N-substituted cyclic iminocarbonates, which are considered to
