Abstract

Reactions of 2-hydroxyimino-3-methyl-2, 3-dihydrobenzothiazole derivatives (1) with Grignard reagents gave 2-hydroxyimino (1e) and 2-(substituted imino)-3-methyl-2, 3- dihydrobenzothiazoles as major products, where 1e was reduced by excess Grignard reagents to 2-imino derivative. On the other hand, reactions of 1 with organolithiums afforded o-(methylamino) phenyl sulfides as a major product.
