%X The kinetics of protodemercuration, or displacement of the HgCl group by hydrogen, have been measured for phenylmercuric chloride, and also for its meta and para methyl-, chloro-, and methoxy-substituted derivatives. The reactions of the compounds with aqueous alcoholic hydrochloric acid were first order in RHgC1, first order in hydrogen ion, and zero order in chloride ion. At 70&quot; the relative rates, which were largely determined by entropy factors, were: phenyl, 1; p-tolyl, 7; m-tolyl, 2.4; p-chlorophenyl, 0.67; m-chlorophenyl, 0.26; p-methoxy, 150; m-methoxy, 0.71. A plot of log k against &#963;+ gives a &#961; value of -2.44, and correlation coefficient of 0.986.
