Palladium(II) perfluorooctanesulfonate [Pd(OSO2Rf8)2] catalyses the highly efficient Suzuki reaction in the presence of a catalytic amount of perfluoroalkylated-pyridine as a ligand in a fluorous biphase system (FBS). The fluorous phase containing the active palladium species is easily separated and can be reused several times without a significant loss of catalytic activity.
在氟双相体系(FBS)中,在催化量的全氟烷基化吡啶作为配体存在下,全氟辛烷磺酸钯(II)[Pd(OSO 2 R f8)2 ]催化高效的Suzuki反应。含有活性钯物质的氟相很容易分离,可以重复使用几次,而不会显着降低催化活性。
