Baylis–Hillman reaction promoted by a recyclable protic-ionic-liquid solvent–catalyst system: DABCO–AcOH–H2O
摘要:
A recyclable protic-ionic-liquid solvent-catalyst system, DABCO-AcOH-H2O, has been developed and used in the Baylis-Hillman reaction of aromatic aldehydes, aliphatic aldehydes, and cinnamaldehydes with acrylates and acrylonitrile, showing comparable performance to free DABCO in traditional solvents. The DABCO-AcOH-H2O solvent-catalyst system could be reused for at least five times without significant loss of activity. (C) 2009 Elsevier Ltd. All rights reserved.
