Abstract

The kinetic of deuteration of β-phenylpropionic acid with D2O acidified with HCl in the presence of homogeneous K2PtCl4 catalyst has been investigated in the 100–130°C temperature interval. The quasi-unimolecular H/D exchange rate constants at 100 and at 130°C, corresponding to fast H/D exchange process, have been deduced by analysis of the composite integrated NMR signal of the substituted benzene ring hydrogens; the Arrhenius activation energy for this exchange was estimated.
