Synthesis of Mo(CO)2(η3-PPh2(o-C6H4)C(O)H)2 and its reaction with C60
摘要:
Reaction of Mo(CO)(3)(NCMe)(3) and PPh2(o-C6H4)C(=O)H (abbreviated as PCHO) at room temperature affords Mo(CO)(2)(eta(3)-PCHO)(2) (1), while compound 1 and the phosphine-imine complex Mo(CO)(4)(eta(2)-PPh2(o-C6H4)CH=NMe) (2) are obtained by using Mo(CO)(3)(eta(3)-(MeNCH2)(3)) as the reactant. Thermal reaction of 1 with C-60 products Mo(CO)(2)(eta(4)-(PPh2(o-C6H4)CH)(2))(eta(2)-C-60) (3) in low yield, apparently through coupling of the formyl moieties. The structures of 1 and 3 have been determined by an X-ray diffraction study. The two aldehyde groups of 1 and C-60 ligand of 3 are coordinated to the molybdenum atom in a pi-fashion.
