| Abstract: | A series of biaryl compounds containing thiazole rings were prepared by using Pd(PPh3)4 as catalyst through the Pd-catalyzed Suzuki cross-coupling reactions of 2-bromothiazole with different substrates of phenylboronic acid.In these reactions,several factors including the influences of bases,solvents and Pd catalysts on the reactions were investigated through single-factor approach,and the optimum reaction condition was obtained.Then the effects of different molecular structures on the reaction were discussed. |
