Maulana I, Lonnecke P, Hey-Hawkins E: Platinum (II) and palladium (II) complexes of chiral P-Cl functionalized bis-phosphino ortho-carbaboranes. Inorg Chem. 2009 Sep 7;48(17):8638-45.
Platinum (II) and palladium (II) complexes of chiral P-Cl functionalized bis-phosphino ortho-carbaborane are readily obtained from reactions of chiral bidentate phosphino carbaborane ligands rac-1,2-(PRCl)(2)(C (2) B (10) H (10)) with [MCl (2)(COD)] (M = Pd, Pt; COD = 1,5-cyclooctadiene) to give cis-rac-[MCl (2){1,2-(PRCl)(2)(C (2) B (10) H (10))}] (M = Pt, Pd; R = (t) Bu, Ph, NEt (2), NPh (2)). cis-rac-[MCl (2){1,2-(P (t) BuCl)(2)(C (2) B (10) H (10))}] [M = Pt (1), Pd (6)] decompose in solution in toluene or dichloromethane at room temperature over several weeks with formation of the corresponding dinuclear platinum and palladium complex with two nido-carbaboranyl phosphine ligands, (R (P),R (P),S (P),S (P))-[{M (7,8-{P (t) BuCl}(2) C (2) B (9) H (10))(mu-Cl)}(2)] [M = Pt (2), Pd (7)], among other decomposition products. |
