Heterometallic complexes by transmetalation of alkynyl groups from copper or silver to allyl palladium complexes: Demetalation studies and alkynyl homocoupling

The reaction of [Pd(η3-allyl)ClL] (L = AsPh3, PPh3) with [M(Ci - CR)]n (M = Cu, Ag; R = nBu, Ph) leads to transmetalation of the alkynyl group from M to Pd. However, the group 11 metal stays η2-bound to the new Pd-alkynyl fragment and heterometallic Pd-M complexes are formed with different nuclearities depending on M: [{Pd(η3-allyl)(alkynyl)L}CuCl] 2 (3, 4) or [{Pd(η3-allyl)(alkynyl)L}2AgCl] (5, 6). The M-containing fragment can be eliminated to give the actual transmetalation complex [Pd(η3-allyl)(alkynyl)L] by adding an excess of arsine or phosphine, whereas amines do not have this effect. Allyl-alkynyl reductive elimination is a slow process; therefore, complexes 3-6 cleanly decompose by dimerization (homocoupling) of the alkynyl group. In the decomposition process reversible alkynyl transmetalation from Pd to Cu has been observed.
