Catalytic Conversions in Water. Part 22: Electronic Effects in the (Diimine)palladium(II)-Catalysed Aerobic Oxidation of Alcohols

The electronic effects in the (diimine)Pd-(II)-catalysed aerobic oxidation of alcohols were investigated from the viewpoint of both the catalyst and the alcohol. A 'push-pull' mechanism is operative, where both electron-donating substituents on the benzyl alcohol (ρ = -0.58) and electron-withdrawing groups on the 4,4′-disubstituted-2,2′-bipyridine ligand (ρ = +0.18) increase the reaction rate. The results indicate partial reduction of the palladium centre in the transition state of the rate-limiting step.

We report the syntheses of 2,2'-bipyridine-4,4'-disulphonic acid (H2bp-4,4'-ds) and 2,2'-bipyridine-5-sulphonic acid (Hbp-5-s), and several ruthenium(II) complexes derived therefrom, including 4-, 2- (bipy=2,2'-bipyridine), , and - and their 2,2'-bipyridine-4,4'-dicarboxylic acid (H2bpdc) analogues, viz. 4-, 2-, and .Some novel thioalkyl derivatives of 2,2'-bipyridine, including 4,4'-di(methylthio)-2,2'-bipyridine, 4,4'-di(ethylthio)-2,2'-bipyridine, and 4,4',6,6'-tetra(methylthio)-2,2'-bipyridine, were also prepared and characterised during the course of this investigation.The luminescent states of the complexes 4-, 2-, 4-, 2-, and were studied using variable-temperature lifetime measurements.Studies of the quenching of 2+>*, >*, 2->*, and 4->* by 1,1'-dimethyl-4,4'-bipyridinium bromide (methyl viologen) in aqueous solution as a function of ionic strength have demonstrated that the effects of charge in these electron-transfer reactions can be understood in terms of conventional theories of ionic reactions whilst, at the same time, confirming the effective charges of the ruthenium(II) complex ions.The rate constants for the quenching of 4->* and 2->* by copper(II) ions in neutral aqueous solution show unusual (non-Arrhenius) temperature dependences.A novel kinetic scheme involving parallel inner- and outer-sphere quenching mechanisms has been proposed to account for the observed behaviour.The luminescence decay of >* in the presence of aqueous copper(II) ions at pH 3.5 is non-exponential.This is interpreted in terms of a combination of static and dynamic quenching effects.
