General description
Application
- Phenazine and quinoxaline derivatives via a condensation reaction between o-phenylenediamines and 1,2-dicarbonyl compounds.
- Imidazole derivatives via one-pot multicomponent condensation reaction of aromatic aldehydes, benzil, aliphatic, and aromatic primary amines.
NaBH4 supported on MgSO4 7H2O can be used as an efficient catalyst for the reduction of α, β-unsaturated carbonyl compounds to corresponding alcohols.
