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.
2-羟基亚氨基-3-甲基-2,3-二氢苯并噻唑衍生物 (1) 与格氏试剂反应得到 2-羟基亚氨基 (1e) 和 2-(取代亚氨基)-3-甲基-2,3-二氢苯并噻唑作为主要产物,其中 1e 被过量格氏试剂还原为 2-亚氨基衍生物。另一方面,1 与有机锂反应得到邻(甲基氨基)苯基硫化物作为主要产物。
