Abstract

1,8-Diaminonaphthalene reacts selectively with 1 equiv. of 9-BBN to form a bridging amine–aminoborane, and with 2 equiv. of 9-BBN to form a non-bridging bis(aminoborane); these aminoboranes give rise to a novel diaminoborate (4e,1-) ligand system by reactions with dimethylamides of titanium and zirconium.
