Abstract

The kinetics of deuteriation of phenylacetic acid with D2O acidified with DCl in the presence of homogeneous K2PtCl4 catalyst has been investigated in the 100–130°C temperature interval. The quasiunimolecular H/D rate constants at 100 and 130°C corresponding exchange processes in α-position in side chain and para position of the substituted benzene ring were determined by NMR integration signal. The same constants for ortho and meta positions have been deduced by analysis of the composite NMR signal, and the Arrhenius activation energies for the exchange reactions were estimated.
