Intramolecular Cyclisations of Nitrile Imines bearing a Thioether Function
N-Aryl nitrile imines bearing a thioether function in the ortho-position were generated in situ on treating the corresponding hydrazonyl chlorides with triethylamine in boiling benzene.In all cases, the major products were 4,1,2-benzothiadiazines arising from intramolecular participarion of the sulphur and subsequent evolution of transient cyclic ylides.Minor products due to an intramolecular 1,3-dipolar cycloaddition were sometimes obtained.
