일반 설명
Diethyl phosphite is the organophosphorus compound used as a phosphorylating agent in organic synthesis.
애플리케이션
Applications of diethyl phosphite (DEP):
- It can undergo condensation with aldehydes or ketones and an amine to form α-aminophosphonates under solvent-free and catalyst-free conditions.
- Reduction of gem-dibromo derivatives using diethyl phosphite in the presence of triethylamine gives monobromocyclopropanes.
- Along with 4-dimethylaminopyridine, it can be used as a ligand for nickel-catalyzed cross-coupling of aryl and heteroaryl bromides, chlorides or sulfonates with arylzinc reagents.
- It can be used for the catalytic asymmetric hydrophosphonylation of enones in the presence of a dinuclear zinc complex to form γ-oxo-phosphonates.
- DEP can undergo Michael addition to α,β-unsaturated malonates to form β-phosphonomalonates in the presence of recyclable nano γ-ferric oxide-pyridine based catalyst.
