Sequential dehydrogenative borylation/hydrogenation route to polyethyl-substituted, weakly coordinating carborane anions

Abstract:

Treatment of Rh(PPh3)2(1-H-closo-CB 11H11) with ethene results in dehydrogenative borylation to form the vinyl-borate complex Rh(PPh3)2(1-H-7/12- (H2C=CH)-closo-CB10H10) as a mixture of 7- and 12-isomers. Further dehydrogenative borylation does not occur; this is accounted for by the strong binding of the vinylcarborane to the {Rh(PPh 3)2}+ fragment through C=C and B-H interactions. Addition of H2 results in hydrogenation of the vinyl group and the quantitative formation of the B-ethylcarbora...
