摘要：A series of simple, efficient, stable and recoverable rare earth metal pentafluorobenzoates [RE(Pfb)(3)] have been synthesized for the first time. A highly efficient and environmentally friendly synthesis of 2,4-disubstituted quinolines catalyzed by Yb(Pfb)(3) via one-pot reaction of aldehydes, alkynes and amines under solvent-free conditions has been explored.
