These are generally obtained by the combination of the respective dichlorophosphine Ar-PCl 2 with zinc powder and an excess of PMe 3 , whereby PMe 3 acts as the active reductant (with concomitant formation of Cl 2 PMe 3 ), 11,12 and stabilizing base. Using ArP=PMe 3 in the reaction with aldehydes (note ketones cannot be converted using this methodology)…”
