Metal-assisted reactions: part 19. Burst kinetics in heterogeneous catalytic transfer hydrogenolysis

Abstract

Arene formation by catalytic transfer hydrogenolysis of aryloxytetrazolyl ethers in the liquid-phase shows biphasic concentration-time curves which indicate rate-limiting dissociation of heterogeneous complexes between catalyst and one of the reaction products, a tetrazolone. A dependence of catalytic reaction rate on pH and following modifications made to the catalyst are reported also.
