attributed to the formation of adducts between either 5 or 7 and the free phosphine (Me3Si)2CH}(C6H4-2-CH2NMe2)PH (9) and interconversion between diastereomers of these adducts. Adductformation is observed only in polar solvents and may be associated with the formation of weakly bound [[(Me3Si)2CH}(C6H4-2-CH2NMe2)P]E(L)]+···Cl− ion pairs in solution. The dynamicbehavior of 8 has been studied by
