Abstract

Nucleophilic substitution of 4, 7-dichloro-3, 8-diphenyl-1, 2-diazocine with arenethiols gave stable 4-arylthio-7-chloro-and/or 4, 7-bis (arylthio)-1, 2-diazocines. Unsymmetrical 4, 7-bis (arylthio)-and 4-acetoxy-7-phenylthio-1, 2-diazocines were also prepared from 4-chloro-7- phenylthio-1, 2-diazocine. Thermolysis of all the diazocines afforded only arylthio- substituted pyridines with extrusion of benzonitrile.
