Formation of high-molecular weight polyaminoborane by Fe hydride catalysed dehydrocoupling of methylamine borane

The complex [(PNHP) Fe(H)(CO)(HBH3)] (PNHP = HN(CH(2)CH(2)Pi-Pr-2)(2)) serves as a catalyst precursor for the selective dehydro-coupling of methylamine borane at room temperature, tentatively via an off-metal polymerisation pathway.
