英文摘要：

A novel series of the picolinic acid derivatives containing triarylamine units were synthesized through diazo - reaction, Ullmann reaction and Suzuki coupling reaction. Their molecular structures were characterized by H NMR and element analysis. The influence of the phase - transfer catalysis on the Ullmann reaction and the effect of molecular structures of bromo - triarylamines on Suzuki coupling reaction were investigated. The results show that Ullmann reaction and Suzuki coupling reaction exhibited a good yield of 48.9% and 25.8%, respectively. The approach is available to synthesize picolinic acids derivatives .
