Quaternization of 1 with 2,5-dimethylbenzyl chloride gave 1,3-bis(2,5- dimethylbenzyl)benzimidazolium chloride (2) salt. The reaction of 2 with palladium(II) acetate, PPh3, LiCl and Et3N gave [PdCl2{1,3-bis(2,5-dimethylbenzyl)benzimidazolin-2-ylidene}(PPh3)] (3) complex. The prepared compounds were characterized by spectroscopic methods and elemental analysis. The palladium complex 3 was used as catalyst in Suzuki–Miyaura cross-coupling reactions of some aryl bromides and chlorides with phenylboronic acid. In the reactions of the all aryl bromides, the catalyst displayed excellent activity and biphenyl compounds were achieved in 99% yields. High activity was observed with some aryl chlorides.engAraştırma Makalesi10.18466/cbayarfbe.941916
