Mercuric Salt

It has been shown that the oxidation of organomercuric salts by inorganic mercuric salts is inhibited by oxygen, accelerated to some extent by acids, and will form esters as products even in the presence of much water. Moreover, the system will polymerize acrylonitrile. These evidences of free radical participation are substantiated by the formation of the same products when pernitrous acid replaces inorganic mercuric salt in the system. Kinetic studies show that radicals are involved in a self-regenerating chain in which active monomeric mercurous salt seems to be the carrier.

Kinetic studies were made of the free radical photoinitiated addition of thiophenol to 1-octene and to styrene in the absence of oxygen. In addition to the usual attack, chain transfer, and termination steps, it is found that a reverse reaction accompanies the attack step, [Formula: see text] The rate constants for the thiophenol–styrene reaction were calculated to be [Formula: see text]kt = 2 × 107 liters.moles−1sec.−1. The over-all activation energies for the two reactions were found to be E (1-octene) = 1.2 kcal., E (styrene) = 2.4 kcal.; suggestions are submitted as to why these activation energies are so low. These reactions are compared with n-butyl mercaptan – olefin reactions.
