| Outline of Final Research Achievements |
Iron complex-catalyzed regioselective single hydrophosphination of terminal arylalkyne with secondary phosphine was achieved. Unsymmetric 1,2-bis(phosphino)ethanes with different phosphino groups were obtained by using our catalytic systems. The structures of obtained vinylphosphine, unsymmetric 1,2-bis(phosphino)ethane, and iron catalyst precursors were confirmed by single crystal X-ray diffraction studies. In addition, Selective double hydrosilylation was achieved by using tertiary and secondary silanes with an excess amount of an organonitrile (RC≡N; R = alkyl, aryl) in the presence of a catalytic amount of triirondodecacarbonyl [Fe3(CO)12] and indium trichloride (InCl3). This reaction was also catalyzed by an iron complex containing indium trihalide [Fe(MeCN)6][Fe(CO)4(InCl3)2], prepared by the reaction of Fe3(CO)12 with InCl3. This is a novel report of the combination of a transition-metal complex and an indium source in organic synthesis.
