Ligand synthesis methods for the preparation of ligands having the formula
wherein Q is selected from phosphorus, arsenic and antimony; wherein X1, X2 and X3 are carbon anions; and, wherein R15 is selected from -SO3, -SO2N(R18), -CO2, -PO3, -AsO3, -SiO2, -C(CF3)2O; where R18 is selected from a hydrogen, a halogen, a hydrocarbyl group and a substituted hydrocarbyl group, are disclosed. Also disclosed are methods of complexing the ligands with late transition metals to form catalyst complexes that catalyze polymerization reactions and/or Heck coupling reactions.
揭示了用于制备具有以下式的配体的配体合成方法:其中Q从磷、砷和锑中选择;其中X1、X2和X3是碳阴离子;其中R15从-SO3、-SO2N(R18)、-CO2、-PO3、-AsO3、-SiO2、-C(CF3)2O中选择;其中R18从氢、卤素、烃基和取代烃基中选择。还揭示了将这些配体与后期过渡金属配合形成催化剂复合物的方法,该复合物催化聚合反应和/或Heck偶联反应。
