    • PURPOSE: Provided is a process for the production of methyl 4-pentenoate (M4P) by selectively cross-dimerizing ethylene and methyl acrylate. Methyl 4-pentenoate is a nylon 6,6 intermediate. CONSTITUTION: Disclosed is a process for the preparation of methyl 4-pentenoate, which comprises contacting ethylene with methyl acrylate in the presence of a nickel II catalyst complex of the structure £QNiL1L2|+X-, wherein Q = n3 carbon-based allyl or substituted allyl, L1 = a monodentate trisubstituted phosphine ligand, L2 = a weakly coordinating ligand, X = a non-coordinating or weakly coordinating nonreactive anion; any liquid medium that may be present as solvent or diluent being non-reactive under the conditions of the process and non coordinating; and recovering the crude reaction product. Optionally, methyl 4-pentenoate can be separated from the crude reaction product by conventional methods, although the crude reaction product often can be used in further reactions without separating methyl 4-pentenoate.
    • 目的:提供通过选择性交联二聚乙烯和丙烯酸甲酯来生产4-戊烯酸甲酯(M4P)的方法。 4-戊烯酸甲酯是尼龙6,6中间体。 构成:公开了一种制备4-戊烯酸甲酯的方法,该方法包括在结构为Q Q i N L 1 L 2 | + X 2的镍II催化剂络合物存在下使乙烯与丙烯酸甲酯接触,其中Q = n3碳基烯丙基或 取代的烯丙基,L1 =单齿三取代膦配体,L2 =弱配位配体,X =非配位或弱配位的非反应性阴离子; 可能作为溶剂或稀释剂存在的任何液体介质在该方法和非配位条件下都是非反应性的; 并回收粗反应产物。 任选地,4-戊烯酸甲酯可以通过常规方法与粗反应产物分离,尽管粗反应产物通常可以在不分离4-戊烯酸甲酯的情况下用于进一步反应。
