A new synthesis of aliphatic isothiocyanates from primary amines, convenient for in situ use
Abstract
Primary aliphatic amines react with carbon disulfide in the presence of BOP (benzotriazole-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate 1, giving the corresponding isothiocyanates in good to high yields and high purity; a number of isothiocyanates are synthesized and isolated or generated in situ and treated with a nucleophile.
