Abstract A full report is given on the previously described reaction between 1, 1- diarylethylenes and mercury (II) salts which results in the formation of vinylic organo- mercurials. Experimental procedures and NMR spectra are described in detail. Special attention is paid on the nature of the intermediate common to both substitution and addition in this system. The structure of this intermediate can best be interpreted as β-mercurated ...
