A NOVEL DIAMINOBORATE LIGAND SYSTEM DERIVED FROM 1,8-DIAMINONAPHTHALENE AND 9-BBN - PREPARATION OF TITANIUM AND ZIRCONIUM COMPLEXES AND CRYSTAL-STRUCTURE OF THE TITANIUM COMPLEX
G. Barhaim et al., A NOVEL DIAMINOBORATE LIGAND SYSTEM DERIVED FROM 1,8-DIAMINONAPHTHALENE AND 9-BBN - PREPARATION OF TITANIUM AND ZIRCONIUM COMPLEXES AND CRYSTAL-STRUCTURE OF THE TITANIUM COMPLEX, Chemical communications, (2), 1997, pp. 229-230
1,8-Diaminonaphthalene reacts selectively with 1 equiv. of 9-BBN to fo
rm 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.
