Metal-assisted reactions. Part 16.: Investigation of mechanisms of heterogeneous liquid phase catalytic transfer hydrogenolysis through deuterium-labelling

Hydrogen isotope studies have shown that heterogeneous catalytic transfer hydrogenolysis of C-O bonds in tetrazolyl ethers of phenols (1) in the liquid phase proceeds via direct transfer of hydrogen from an active hydrogen donor centre to the ether on the catalyst surface and not through transfer of hydrogen atoms from the catalyst surface.
