5-Methyl-1,3,2-benzodithiaborole and related compounds

Abstract

Reactions of 2-chloro-5-methyl-1,3,2-benzodithiaborole (I), obtained from toluene-3,4-dithiol and trichloroborane, with bis(trimethylsilyl)amine and tris(trimethylsilyl)amine have been studied. Tris-(5-methyl-1,3,2-benzodithiaborol-2-yl)amine, bis-(5-methyl-1,3,2-benzodithiaborol-2-yl)amine, and bis-(5-methyl-1,3,2-benzodithiaborol-2-yl)(trimethylsilyl)amine have been prepared. Tributyltin hydride converts (I) into 5-methyl-1,3,2-benzodithiaborole, which forms a stable complex with diethylamine.
