摘要: Abstract The complex [Ru(4,4′-Me2bpy)2(PPh3)(H2O)](ClO4)2 has been synthesized and characterized by elemental analysis, spectroscopic electrochemical methods. E 1 2 vs pH studies are consistent with one-electron, one-proton transfer; at higher the potentials become independent. catalytic activity of investigated 6.5 in homogeneous electrooxidation benzylic compounds. reactivity was found to decrease order 1-phenylethanol ⪢ phthalic alcohol > benzyl 4-methylbenzyl ethylbenzene toluene. Carbon paste electrode (CPE) containing shown oxidations alcohols. Benzyl oxidation CPE is first on substrate concentration for low concentrations controlled diffusion rate from solution.
