Synthesis of Mo(CO)2(η3-PPh2(o-C 6H4)C(=O)H)2 and its reaction with C 60

Reaction of Mo(CO)3(NCMe)3 and PPh 2(o-C6H4)C(O)H (abbreviated as PCHO) at room temperature affords Mo(CO)2(η3-PCHO)2 (1), while compound 1 and the phosphine-imine complex Mo(CO)4(η 2-PPh2(o-C6H4)CHNMe) (2) are obtained by using Mo(CO)3(η3-(MeNCH2) 3) as the reactant. Thermal reaction of 1 with C60 products Mo(CO)2(η4-(PPh2(o-C 6H4)CH)2)(η2-C60) (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 C60 ligand of 3 are coordinated to the molybdenum atom in a π-fashion.

Synthesis of Group 6 metal carbonyl complexes with iminophosphine ligands: Crystal structure of [Mo(Co)4(o-Ph2PC6H4-CH=NMe)]

The synthesis of new molybdenum and tungsten carbonyl complexes with the mixed donor bidentate ligands o-Ph2PC6H4-CH=NR is described. Two series of complexes [M(CO)4(o-Ph2PC6H4-CH=NR)] (M = Mo; R = Me (1a), Et (2a), (i)Pr (3a), (t)Bu (4a), NH-Me (5a). M = W; R = Me (1b), Et (2b), (i)Pr (3b), (t)Bu (4b), NH-Me (5b)) have been prepared by direct reaction of the ligands with the corresponding precursors cis-[M(CO)4(pip)2] (M = Mo or W; pip = piperidine NHC5H10). The new complexes were characterized by partial elemental analyses and spectroscopic methods (IR, 1H, 13C and 31P NMR). The molecular structure of compound 1a (monoclinic, P21/n) was determined by a single-crystal diffraction study. (C) 2000 Elsevier Science S.A.
