Gold conjugate base mechanism

Moving to palladium complexes, related early studies on [PdX(Et4-dien)]+ also indicated the possible operation of a CB mechanism. Hydroxide ions reacted differently to other nucleophiles at these steri-cally hindered molecules in showing a distinct bimolecular (A2) dependence as well as a solvolytic pathway (85). This was unexpected because OH" is known to be a poor nucleophile in these systems, and it led to the proposal of the conjugate base contribution. The ions [PdX-(Et4Me-dien)]+, which have no acidic protons, did not show this behavior. The CBs reacted some 30 times faster than their precursors (a reactivity enhancement somewhat less than their gold(III) counterparts with the same ligands), again probably by an associative route. [Pg.248]
