| Application: | 1,8-Diazabicyclo[5.4.0]un • 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. |
| 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 |
