It has been shown that deoxymercuration (conversion of an α-oxyorganomercurial to the alkene) is a second-order reaction dependent on concentration of the mercurial and of the deoxymercurating acid. Moreover the rate of deoxymercuration increases with basic strength of the alkoxy substituent in the mercurial. This tendency would indicate that the rate was dependent on the strength of the acid used

The kinetics of the cleavage of (trans-2-methoxycyclohexyl)-, (trans-2-ethoxycyclohexyl)-, (trans-2-hydroxycyclohexyl)-, and (trans-2-methoxycyclopentyl)mercuric chlorides by hydrochloricacid have been investigated by a conductivity method. The reaction in alcohol/water mixtures were found to be pseudo-second-order. The enthalpies and entropies are discussed in relation to the nature of the organic
