A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 564483-18-7, Name is 2-(Dicyclohexylphosphino)-2′,4′,6′-tri-i-propyl-1,1′-biphenyl, molecular formula is C33H49P. In a Patent，once mentioned of 564483-18-7, name: 2-(Dicyclohexylphosphino)-2′,4′,6′-tri-i-propyl-1,1′-biphenyl
The invention discloses a process for preparing 2-bicyclic hexyl phosphine -2, 4, 6-tri-isopropyl biphenyl method, including: the 2-halo -2, 4, 6-tri-isopropyl biphenyl after low temperature lithium, and dicyclohexyl phosphine reaction. The method of the present invention is not only high in productivity, and after treatment is simple, easy to operate. According to the present invention a preferred embodiment, in order to 2, 4, 6-tri-isopropyl benzene halide kind as the starting material, and the low temperature lithiation reaction halogeno benzene O, to obtain 2-halo -2, 4, 6-tri-isopropyl biphenyl; the continued low temperature lithiation reaction with dicyclohexyl phosphine, preparation 2-bicyclic hexyl phosphine -2, 4, 6-tri-isopropyl biphenyl. The route raw materials are easy, simple operation, can be obtained high-yield, high-purity product, is in particular suitable for large-scale industrial production. (by machine translation)
