摘要

4 5 thioether 2 (67% yield). When 2 was allowed to react with excess methanethiol anion (lithium salt) in cold DMF (ice bath) for 1 h, the product obtained was 3, 4, 5-tris (methylthi0) benzotrifluoride (3, 95%). Similar treatment of 1 yielded 3 directly (74%). The same reaction with 2-chloro-3, 5-dinitrobenzotrifluoride (4) 8 gave 2, 3, 5-tris (methylthio) benzotrifluoride (5, 7090). The bis thioether 6a (61%) could be obtained
