Anderson 1 , John A. Soderquist ∗ , George W. Kabalka Add to Mendeley Methylenetriphenylphosphorane is prepared from methyltriphenylphosphonium bromide by its deprotonation using a strong base like butyllithium: Ph3PCH3Br + BuLi → Ph3PCH2 + LiBr + BuH The phosphorane is generally not isolated, instead it is used in situ. The estimated pKa of this carbon acid is near 15. Potassium tert-butoxide has been used in place of butyl lithium. Sodium a…
