Application

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

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.[1]
• 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.

Other Notes

Amidine base used for dehydrohalogenation reactions to olefins; Further important applications are e.g.: esterification of carboxylic acids with alkyl halides; Alkylation and acylation of active methylene compounds.
