| (FORMYLMETHYLENE)TRIPHENYLPHOSPHORANE Usage And Synthesis |
| Chemical Properties | pink to brown crystalline powder | | 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. | | Uses | Wittig reagent for the conversion of aldehydes and ketones to two-carbon homologated, α,β-unsaturated carbonyl compounds. | | Purification Methods | Recrystallise 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.
