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.

(11) Data for 2, 4, and 5 were collected with a Bruker Kappa Apex II
CCD diffractometer at 100 K, with a Nonius KCCD diffractometer at
150 K, and on I19 (EH1) at the Diamond Light Source at 150 K,
respectively. 2 and 4 were solved and refined using SHELXS/XL-97
(see: Sheldrick, G. M. Acta Crystallogr. 2008, A64, 112). 5 was
solved using SIR92 (see: Altomare, A.; Cascarano, G.; Giacovazzo, C.;
Guagliardi, A.; Burla, M. C.; Polidori, G.; Camalli, M. J. Appl. Crystallogr.
1994, 27, 435.) and refined using CRYSTALS (see: Betteridge, P. W.;
Carruthers, J. R.; Cooper, R. I.; Prout, K.; Watkin, D. J. J. Appl.
Crystallogr. 2003, 36, 1487). The crystallographic data for 2, 4, and 5
have been deposited with the CCDC as entries 823663, 823664, and
823665, respectively.
