Mercuric reaction- -boronic esters

In further studies, Matteson et a/.10,11 reported relative rates of substitution of various boronic esters by mercuric chloride details are given in Table 3. The solvent used was a mixture of ethanol (88 %), water (8 %), and glycerol (4 %), buffered with sodium acetate and acetic acid, and reactions were run in the presence of added sodium chloride. Under these conditions, the kinetics of reaction of benzylboronic ester with mercuric chloride were found to obey the rate law... 

Second-order rate coefficients for the reaction of some boronic esters with mercuric chloride in methanol were reported by Matteson and Allies13 details are in Table 4. The solution was buffered with sodium acetate/acetic acid, and the observed rate equation was found to be... 

Reaction takes place at 0-30° in the presence of boron trifluoride and mercuric oxide. The reaction is reversible in the presence of mercury salts and allows the preparation of vinyl esters from vinyl acetate and higher-molecular-weight carboxylic acids. ...
