Abstract

The highly efficient transformation of CX2 (O, S) into valuable chemicals at atmospheric pressure is an attractive topic. A novel method of preparing quinazoline derivatives by capturing CX2 (O, S) in reusable, room-temperature, reversible ionic liquids (ReILs) with high yields (up to 98%) at 40 °C and atmospheric pressure was developed in this paper. The different reaction conditions were optimized and the products were easily separated from the ReILs which could be reused at least six times without considerable loss in yield. The plausible mechanism of capturing CX2 (O, S) in the ReILs was proposed and it provides a green, efficient protocol to capture CX2 (O, S) in ReILs to synthesize quinazoline derivatives.
