摘要

An improved and rapid one-pot synthesis of 5,6-diarylsubstituted-1,2,4-triazines in a mixture of room-temperature ionic liquid 1,3-dibutylimidazolium bromide [Bbim] + Br − and dimethylsulfoxide (DMSO) is described without the need for any added catalyst. Different polar aprotic solvents were screened along with ionic liquids and a synergistic effect with DMSO has been found. The predominance of one regioisomer over the other has also been studied with varying ...
