Outline of Final Research Achievements

Rare examples of metal complexes bearing the ligands with two Lewis acidic centers were obtained. Complexation of the tri-tert-butylazadiboriridine (1) with gold(I) complexes AuCl(L) resulted in formation of three structurally different complexes depending on the metal co-ligands. When a weak Lewis base (L=SMe2) is used, a symmetrical complex [eta2-B,B-B(tBu)N(tBu)B(tBu)]AuCl (2) was obtained with a loss of the ligand. In cases where phosphines were used, B-B bond cleavage accompanied by either a halide (L=PPh3) or phosphine (L=PMe3) migration proceeded to form different borylgoldborane complexes (3 and 4). A similar product (5) that is isostructrual to 3 was obtained by addition of dimethylaminopyridine (DMAP) to 2-4. The formation, structures and reactivity of 2-5 have been investigated, showing the effects of the second Lewis acidic center. A gold(I) complex 6 bearing a 5-membered heterocycle obtained from 3 and tert-butylisonitrile is also reported.
