Kinetics and Mechanism of Halogen-bridge Cleavage in Dimethylaminomethylphenyl-C1,N Pallada- and Platina-cycles by Pyridines. Pressure Effects, and Crystal Structures of the N,N-cis Reaction Product, its N,N-trans Orthometallated Analogue and a Dimer of Similar Reactivity
An ambient and high-pressure stopped-flow kinetic study of the halogen-bridge cleavage reaction in the pallada- and platina-cycles <2> (M = Pd or Pt; R = H, 4-MeO, 5-Me or 5-F; X = Cl or I) by a series of substituted pyridines in chloroform as solvent revealed that it is a fast, associatively driven second-order process, with strong steric rather than electronic demands.Substituent effects and activation parameters (DeltaH(excit.),DeltaS(excit.) and DeltaV(excit.)) were in full accord with the proposed associative mechanism.The Pd dimers transformed into N,N-trans monomers of the type (py = pyridine).In contrast, the Pt counterparts afford N,N-cis species under the same conditions.The geometry of the N,N-cis complex X(py)>, as well as of the N,N-trans platinacycle Cl(py)>, has been confirmed by X-ray crystallography.The most striking structural differences in the N,N-cis and N,N-trans related platinacycles are the Pt-Cl and Pt-N(py) bond distances <2.300(1) and 2.408(5), 2.138(4) and 2.02(1) Angstroem, respectively>.The crystal structure of trans-<(n-Bu3P)IPd(mu-I)2PdI(P-n-Bu3)> has also been determined and used to account for its similar reactivity to <2> in the bridge-splitting reaction.
