A new method of synthesis of o- and m-carboranyl-B-thiols and o- and m-carboranyl-B,B'-dithiols via the electrophilic sulfuration of o-, m-carboranes with S2Cl2 in the presence of AlCl3 is described.The reaction of o-carborane with excess S2Cl2 in the presence of AlCl3 gives B,B',B'',B'''-tetrathiol-o-carborane.Various chemical conversions of carborane sulfur derivatives are studied.A description is made of carbonyl derivatives of di-, tetra- and hexavalent sulfur, such as sulfenyl chlorides, thiocyanates, disulfides, alkyl- and aryl sulfides, aryl sulfones and aryl sulfoxides. 9-m-Carboranylsulfinic acid was found to readily disproportionate to thiosulfonate and sulfonic acid.The chemical behaviour of o- and m-carboranyl sulfur derivatives in which the sulfur is ?-bound to the six-coordinated boron atom was also found to be similar to that of organic sulfur derivatives.
