One-step synthesis of 4-oxoimidazolinium salts from N, N′-diaryl-1,4-diazabuta-1,3-dienes and trialkyl orthoformates

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....
