Formation of carboxylate complexes from the reactions of CO2 with ethylene complexes of molybdenum and tungsten. X-ray and neutron diffraction studies

Carbon-carbon bond formation by coupling of ethylene with carbon dioxide on the coordination sphere of the metal center in the electron-rich complexes trans-M(C2H4)2(PMe3)4 (M = Mo, 1; M = W, 2) can be effected under mild conditions by reactions of 1 and 2 with CO2. These afford the binuclear hydrido acrylate derivatives [MH(OOCCH=CH2)(C2H4)(PMe3) 2]2 (M = Mo, 3; M = W, 4), which contain bridging μ2-η3,η1-acrylate ligands. Hydrogenation of 3 and 4 in the presence of PMe3 provides the hydrido propionates MoH(η2-OOCCH2CH3)(PMe3) 4 (5) and WH3(η1-OOCCH2CH3) (PMe3)4 (6), but the direct reaction of 1 and 2 with a 1:1 mixture of CO2/H2 yields instead the hydrido carbonate derivatives MH2(η2-CO3)(PMe3)4 (M = Mo, 7; M = W, 8). The hydrido allyl compounds MH(η3-C3H5)(PMe3)4 (M = Mo, 9; M = W, 10), formed by sodium amalgam reduction of MCl4(PMe3)3 under propylene, do not react with CO2 with carbon-carbon bond formation but rather with reductive elimination of propylene and production of the adduct transMo(CO2)2(PMe3)4 and various carbonate complexes. The crystal and molecular structures of 3, 4, and 6 have been determined by X-ray studies, and, in addition, a low-temperature (20 K) neutron diffraction analysis of 4 has been performed. 3 is monoclinic, P21/n, with a = 12.117 (8) A?, b = 15.072 (5) A?, c = 17.700 (5) A?, β = 102.18 (3)°, Z = 4, and R = 0.032, while 6 is monoclinic, P21/c, with a = 12.813 (2) A?, b = 8.903 (3) A?, c = 21.671 (3) A?, β = 88.62 (1)°, Z = 4, and R = 0.048. The crystal of 4 used for the neutron diffraction study is monoclinic, P21/c, with a = 14.23 (1) A?, b = 11.80 (1) A?, c = 20.58 (2) A?, β = 104.94 (6)°, Z = 4, and R = 0.034.
