Abstract
We report the first insertion step at a metal center for the catalytic dehydropolymerization of H(3)B center dot NMeH(2) to form the simplest oligomeric species, H(3)B center dot NMeHBH(2)center dot NMeH(2), by the addition of 1 equiv of H(3)B center dot NMeH(2) to [Ir(PCy(3))(2)(H)(2)(eta(2)-H(3)B center dot NMeH(2))] [BAr(4)(F)] to give [Ir(PCy(3))(2)(H)(2)(eta(2)-H(3)B center dot NMeHBH(2)center dot NMeH(2))] [BAr(4)(F)]. This reaction is also catalytic for the formation of the free linear diborazane, but this is best obtained by an alternative stoichiometric synthesis.
