Reactions of Aldonitrones with Phenylphosphonothioic Dichloride and Related Compounds. Formation of 2-Arylbenzothiazoles from α,<i>N</i>-Diarylnitrones
Reactions of α-aryl-N-methylnitrones with phenylphosphonothioic dichloride (1), diphenylphosphinothioic chloride (6), or thiophosphoryl trichloride (7) gave N-methylbenzamide and N-methylthiobenzamide derivatives, and the latter became major in the presence of tertiary amine. α,N-Diarylnitrones (4) reacted with 1 to give 2-arylbenzothiazoles (5) at room temperature in moderate yields. Reaction of 4
