A ruthenium phosphine complex is represented by the formula
wherein R-BINAP represents a tertiary phosphine represented by
wherein the R's are the same and each represents hydrogen, methyl or t-butyl, S represents tertiary amine, y is 0 or 1, and when y is 0.x=2, z=4 and p=1 and when y is 1, x=1.z= 1 and p = 0.
The illustrated amine is triethylamine.
The complex is prepared by reacting a complex of ruthenium chloride and cyclooctadiene with the R-BINAP phosphine in the presence of a tertiary amine, in a solvent
The complex is useful as a catalyst in industrial reac tions. e.g. synthesis under pressure for several hours of N-benzoyl phenylamine or of a lactone, especially for assymetric hydrogenation or dehydrogenation.
钌膦络合物由式表示
其中 R-BINAP 代表叔膦,由以下式子表示
其中 R 相同,各代表氢、甲基或叔丁基,S 代表叔胺,y 为 0 或 1,当 y 为 0.x=2, z=4 和 p=1 时,当 y 为 1 时,x=1.z=1 和 p=0。
图中的胺为三乙胺。
该络合物是通过氯化钌和环辛二烯的络合物与 R-BINAP 磷化氢在叔胺存在下于溶剂中反应制备的。
该络合物在工业反应中可用作催化剂,例如在加压数小时的情况下合成 N-苯甲酰基苯胺或内酯,特别是用于同义氢化或脱氢反应。
