摘要

The reaction of bisbenzimidazolium salt with Grignard reagents and a new synthetic method of α-diketons from bisbenzimidazolium salt and Grignard reagents are reported. The structures urres of all a-diketones are characterized by elemental analyses, infrared spectroscopy and 1H NMR spectroscopy. The infuences of the various Grignard reagents on the yield of α-diketones and the mechanism are discussed, and a new convenient synthetic method for α-diketones is provid-ed.
