Metal-catalysed dehydrocoupling: {Ir(PCy3)2(H)2}+ has been used to study the chemistry of the aminoborane H2B[BOND]NMe2, a central component in the dehydrocoupling of H3B⋅NMe2H. A mechanism that involves the metal in both dehydrogenation and oligomerisation, in addition to competitive off-metal dimerisation is suggested. The interaction between metal centre and H2B[BOND]NMe2 has also been used to drive the retrodimerisation of [H2BNMe2]2.
