Application

1,8-Diazabicyclo[5.4.0]undec-7-ene can be used:
  • To mediate the aza-Michael addition of nitrogen nucleophiles to α,β-unsaturated carbonyl compounds.
  • As a nucleophilic catalyst for the esterification of carboxylic acid with dimethyl carbonate.
  • As a bidentate ligand in copper (I) bromide mediated atom transfer radical polymerization of methyl methacrylate.
  • As an efficient catalyst for the transesterification of dimethyl carbonate with glycerol.
Amidine base used for dehydrohalogenation reactions to olefinscitation; Further important applications are e.g.: esterification of carboxylic acids with alkyl halidescitationcitation; Alkylation and acylation of active methylene compoundscitation
