1,2-Bis(mercapto)-o-carborane reacts with a variety of boranes including diborane and alkyl-, aryl-, chloro-, and aminoboranes to produce 1,2-(2′-substituted 1′,3′,2′-dithiabora)-o-carboranes. Reaction with trichloroborane in a 1:1 mole ratio gives a good yield of 1,2-(2′-chloro-1′,3′,2′-dithiabora)-o-carborane, some reactions of which are reported. Reaction of 1,2-bis-(mercapto)-o-carborane with trichloroborane in a 2:1 mole ratio gives what appears to be a novel ring system in which boron is tetracoordinated by sulfur.
