Mechanism of Migration of Ancillary Ligands in Binuclear Palladium(II) Allyl Complexes

The kinetics and mechanism of the reaction between the binuclear cationic complexes 1)CR3=NR2>Pd(η3-CH2CR4CH2)>ClO4 1 = R2 = C6H4OMe-p, R3 = H, Me, or Ph, R4 = H or Me, L = P(C6H4X-p)3, X = Cl, H, or OMe; R1 = C6H4OMe-p, R2 = R3 = R4 = Me, L =PPh3 or PMePh2> and the anionic allyl derivatives 3-2-R4C3H4)>, (A), leading to the binuclear zwitterionic compounds 1)CR3=NR2>Pd(η3-CH2CR4CH2)>, (2), together with the neutral palladium-allyl products 3-2-R4C3H4)L>, (B), have been studied in 1,2-dichloroethane.This reaction, wich involves exchange of the ancillary ligands L and Cl(1-) between the reactants (1) and (A), proceeds via two parallel steps with rate constants k1 and k2.The faster step consists of a rapid pre-equilibrum association (K) to give the intermediate (1...A), which then rearranges slowly (k2) via opening of the five-membered α-di-imino-cycle in a proposed three-metal transition state.The parallel slower step is formulated as a rate-determing (k1) intramolecular rearrengement of (1) to a labile intermediate (1*), which reacts rapidly with (A) to yield the final products.For this step, the activation process is proposed to involve unassisted α-di-imino ring opening and dissociative exchange of L.The mechanism proposed is based on the activation parameters and on rate effects exerted by the α-di-imino-substituents R2, R3, by the allyl group substituent R4, and by the electronic properties of L.In general, the rate constant k1, k2 and the pre-equilibrum constant K decrease with increasing electron-releasing abilities of the C- and N-imino-substituents; k2 is also depressed by increasing steric demands of the R3 and R4 groups.An increase in the electron-donor properties of L will also bring about a decrease in the overall reaction rate.The effects are generally related to the ease of opening and rearrangement of the ?,?-N,N-chelated α-di-imine in (1) together with the lability of the Pd-L bond.
