Abstract: We report the first insertion step at a metal center for the catalytic dehydropolymerization of H3B·NMeH2 to form the simplest oligomeric species, H3B·NMeHBH2·NMeH2, by the addition of 1 equiv of H3B·NMeH2 to [Ir(PCy3)2(H)2(η2-H3B·NMeH2)][BArF4] to give [Ir(PCy3)2(H)2(η2-H3B·NMeHBH2·NMeH2)][BArF4]. This reaction is also catalytic for the formation of the free linear diborazane, but this is best obtained by an alternative stoichiometric synthesis.
