A new multicomponent reaction leading to the formation of an imidazole ring was discovered: N,N′-diaryl-1,4-diazabuta-1,3-dienes reacted with trialkyl orthoformates, chloro(trimethyl)silane and water to give N,N′-1,3-diaryl-4-oxoimidazolinium salts or their tautomers, 4-hydroxyimidazolium salts.
发现了导致形成咪唑环的新多组分反应:N,N '-diaryl-1,4-diazabuta-1,3-dienes 与原甲酸三烷基酯、氯(三甲基)硅烷和水反应生成N,N '-1,3-二芳基-4-氧代咪唑啉盐或其互变异构体,4-羟基咪唑盐。
