Selective double hydrosilylation and double hydroborylation were achieved by using tertiary and secondary silanes and pinacolborane with an organonitrile (RC≡N; R=alkyl, aryl) in the presence of a catalytic amount of an iron complex containing indium trihalide [Fe(MeCN)6][cis-Fe(CO)4(InX3)2], prepared by the reaction of [Fe3(CO)12] with InX3 (X=Cl, Br, I). In both reactions two silyl groups and two boryl groups made bonds selectively with only the nitrogen atom. In addition, this catalytic system could be adaptable to an unprecedented one-pot synthesis of borylsilylamine via catalytic hydrosilylation and hydroborylation of organonitrile. These are novel reports of the combination of a transition-metal complex and an indium source in organic synthesis.
