(FORMYLMETHYLENE)TRIPHENYLPHOSPHORANE Usage And Synthesis
Chemical Propertiespink to brown crystalline powder
UsesWittig reagent for the conversion of aldehydes and ketones to two-carbon homologated, α,β-unsaturated carbonyl compounds.
Uses(Formylmethylene)triphenylphosphorane is used as Wittig reagent. It is also used as Pharmaceutical Intermediates. It is employed as raw material in organic Synthesis, Agrochemicals.
Purification MethodsRecrystallise it from Me2CO, or dissolve it in *C6H6, wash with N NaOH, dry (MgSO4), evaporate, and crystallise the residue from Me2CO. It can be prepared from its precursor, formylmethyltriphenylphosphonium chloride (which crystallises from CHCl3/EtOAc), by treatment with Et3N and extraction with *C6H6.
