  Synthesis, Structure, and Reactivity of (^tBu₂PC₂H₄P^tBu₂)Ni(CH₃)₂ and {(^tBu₂PC₂H₄P^tBu₂)Ni}₂(μ-H)₂

  摘要：

  Oxidative addition of CH3I to (d(t)bpe)Ni(C2H4) (d(t)bpe = (Bu2PC2H4PBu2)-Bu-t-Bu-t) affords (d(t)bpe)-Ni(I)CH3 (I). The reaction of (d(t)bpe)NiCl2 or 1 with the stoichiometric quantity of (tmeda)Mg(CH3), yields (d(t)bpe)Ni(CH3)(2) (2). (d(t)bpe)Ni(I)CD3 (1-d(3)) and (d(t)bpe)Ni(CD3)(2) (2-d(6)) have been prepared analogously. Thermolysis of 2 in benzene affords {(d(t)bpe)Ni}(2)(mu-eta(2):eta(2)-C6H6) (4). The reaction of either 2 or 4 with hydrogen (H-2, HD, D-2) gives {(d(t)bpe)Ni}(2)(mu-H)(2) (3) and the isotopomers {(d(t)bpe)Ni}(2)(mu-H)(mu-D) (3-d) and {(d(t)bpe)Ni}(2)(mu-D)(2) (3-d(2)). According to the NMR spectra, the structure of 3 is dynamic in solution. The crystal structures of 2 and 3 have been determined by X-ray crystallography, Solution thermolysis of 2 or reduction of (dtbpe)NiCl2 with Mg* in the presence of alkanes probably involves a-complex-type intermediates [(d(t)bpe)Ni(eta(2)-R'H)] (R' = e.g. C2H5, A). While the nonisolated [(d(t)bpe)Ni-0] a-complexes A are exceedingly reactive intermediates, isolated 3 and 4 represent easy to handle starting complexes for [(d(t)bpe)Ni-0] reactions. Partial protolysis of 2 with CF3SO3H affords (d(t)bpe)Ni(CH3)(OSO2CF3) (5). Complex 5 reacts slowly with 2 equiv of ethene to give equimolar amounts of [(d(t)bpe)Ni(C2H5)](+)(OSO2CF3-) (6) and propene. The reaction is thought to be initiated by an insertion of ethene into the Ni-CH3 bond of 5 to form the intermediate [(d(t)bpe)Ni(C3H7)(OSO2CF3)] (G), followed by elimination of propene to give the hydride intermediate [(d(t)bpe)Ni(H)(OSO2CF3)] (H), which on insertion of ethene into the Ni-H bond affords 6.

  In a process for preparing an alkali metal or alkaline earth metal salt of an α,β-ethylenically unsaturated carboxylic acid, a) a transition metal-alkene complex is reacted with CO 2 to give a metallalactone, b) the metallalactone is reacted with a base to give an adduct of the alkali metal or alkaline earth metal salt of the α,β-ethylenically unsaturated carboxylic acid with the transition metal complex, and c) the adduct is reacted with an alkene to release the alkali metal or alkaline earth metal salt of the α,β-ethylenically unsaturated carboxylic acid and regenerate the transition metal-alkene complex. The base is selected from alkali metal or alkaline earth metal hydroxides and alkali metal or alkaline earth metal superbases. The alkene is, for example, ethene. The transition metal complex comprises, for example, nickel and a bidentate P,P, P,N, P,O or P,carbene ligand, such as 1,2-bis(di-tert-butylphosphino)ethane.
