Synthesis and versatile reactivity of scandium phosphinophosphinidene complexes

摘要

Deprotonation of phosphinophosphine H PP{N(DIPP)CH CH N(DIPP)} with KCH (C H ) in THF gives a potassium salt K[HPP{N(DIPP)CH CH N(DIPP)}], which subsequently reacts with scandium methyl chlorides [LSc(Me)Cl] or [L′Sc(Me)Cl] to give scandium phosphinophosphinidene complexes and .
