Abstract

1. The reaction of ethyl esters ofα-bromomercuryarylacetic acids proceeds at the carbon atom in dichloroethane and at the oxygen atom in nitromethane. 2. The reaction of mercurated esters with Ar3CBr is accomplished through the preliminary formation of a complex between the reagents and is first order with respect to the complex. The reaction of mercurated esters with Ar3CBr · HgBr2 proceeds according to a bimolecular mechanism. 3. The reactions of arylmercury bromides with tetraphenylbromomethane and its complex with mercuric bromide proceed according to a single mechanism. The reaction with trityl bromide is accelerated by additions of iodide ions.
