phosphine
Application
4-Diphenylphosphanyl-benzoic acid 2-trimethylsilanyl-ethyl ester (DPPBE) was developed as an efficient alternative to triphenylphosphine in the Mitsunobu reaction since the phosphine oxide formed during the reaction can be easily removed during workup.
Reagent for:
- Synthesis of alkenes
- Methylation of aldehydes
- Mitsunobu reactions
