一系列（R_3Q）_2MX_2（R=烷基或芳基; Q= P、As或Sb; M= Ni、Pd或Pt; X=卤素或拟卤素）型配合物已被发现具有不寻常的催化性能。在Pt和Pd络合物的情况下，这些性质通过添加M 'X2或'X4（M '= Si、Ge、Sn或Pb）而大大增强。所得配合物具有催化亚油酸甲酯加氢至单烯阶段的能力，但不能进一步催化。氢化反应是通过顺式双键转化为反式双键，以及双键沿着烃链迁移形成共轭体系来进行的。氢化反应最好用元素氢进行，但在没有氢的情况下也可用甲醇进行。
A series of complexes of the type (R3Q) 2MX2 (R= alkyl or aryl; Q= P, As, or Sb; M= Ni, Pd, or Pt; X= a halogen or pseudohalogen) has been found to have unusual catalytic properties. In the cases of the Pt and Pd complexes, these properties are greatly enhanced by the addition of M'X2 or'X4 (M'= Si, Ge, Sn, or Pb). The resulting complexes have the ability to catalyze the hydrogenation of methyl linoleate to the monoene stage, but no further. The hydrogenation is precededby conversion of cis double bonds to trans, and by migration of the double bonds along the hydrocarbon chain to give a conjugated system. The hydrogenation is best brought about by elemental hydrogen, but it can be effected by methanolin the absence of hydrogen.
