A Cyclobutene-1,2-Bis(imidazolium) Salt as Efficient Precursor of Palladium-Catalyzed Room-Temperature Suzuki-Miyaura Reactions

[摘要]：3,3'-[3,4-Bis(dichloromethylene)cyclobut-1-ene-1,2-diyl]bis(1-methyl-1H- imidazolium) bis(tetrafluoroborate), palladium(II)acetate, and sodium tert-butoxide in toluene catalyze effectively Suzuki-Miyaura cross-coupling reactions of aryl bromides, chlorides, and iodides with arylboronic acids at room temperature.
