Abstract

A new one-step synthesis of isonitriles is described. The starting materials are a primary amine, chloroform, sodium hydride, and the phase-transfer catalyst 15-crown-5 ether, and the solvent is benzene. Five compounds are used to illustrate the features of the new synthesis: 1-adamantyl isocyanide (2a), 2-adamantyl isocyanide (2b), cis-1,8-diisocyano-p-menthane (2c), 2,4,6-trimethylphenyl isocyanide (2d), and trityl isocyanide (2e). The present ...
