PURPOSE: A potassium styrenyl trifluoroborate and a method for preparing the same are provided to easily and quickly prepare various kinds of novel styrenyl compounds. CONSTITUTION: A potassium styrenyl trifluoroborate derivative is denoted by chemical formula 1. A method for preparing the derivative comprises a step of reacting a potassium halo aryl trifluoroborate derivative and an alkene compound under the presence of a palladium catalyst. The palladium catalyst is selected from the group consisting of palladium(II)chloride(PdCl_2), palladium(II) acetate(Pd(OAc)_2), bis(triphenylphosphine) palladium(II) chloride(PdCl_2(PPh_3)_2), bis(dibenzylidene acetone) palladium(0)(Pd(dba)_2), tetrakis(triphosphine) palladium(0)(Pd(PPh_3)_4),[1,1'-bis(diphenylphosphino)-ferocene]palladium(II) dichloride dichloromethane complex (PdCl_2(dppf)_2·CH_2Cl_2), and chloro[(1,3-dimesitylimidazole-2-ylidene)(N,N-dimethylbenzylamine)palladium(II)]. |
