WebMethylenetriphenylphosphorane is prepared from methyltriphenylphosphonium bromide by its deprotonation using a strong base like butyllithium: [1] Ph 3 PCH 3 Br + BuLi → Ph 3 PCH 2 + LiBr + BuH The phosphorane is generally not isolated, instead it is used in situ. The estimated pK a of this carbon acid is near 15.
