A mild, three-component dinitrogen extrusion reaction proceeding at room temperature to give different 1,2-disubstituted benzimidazoles from 2-oxoaldehydes, 4-azidophenol, and benzotriazoles was successfully developed. Mechanistically, this transformation occurs through the benzoquinone imine assisted ring opening/ring closing of a highly unstable RCOCHN1N2 system.

RCOCHN1 N2 系统的苯醌亚胺辅助开环/闭环策略：二氮挤压反应生成苯并咪唑

成功地开发了一种温和的三组分二氮挤压反应，在室温下进行，从 2-氧醛、4-叠氮苯酚和苯并三唑得到不同的 1,2-二取代苯并咪唑。从机制上讲，这种转变是通过苯醌亚胺辅助的高度不稳定的 RCOCHN1N2 系统的开环/闭环发生的。
