Abstract: The reaction of phenyl (bromodichloromethyl) mercury with triethylsilane in benzene at 39.0" was found to be about first order in mercurial and zero order in triethylsilane, and the mechanism shown by eq 6 and 7, which involves a dichlorocarbene intermediate, was suggested, A Hammett study of the reaction of this mercurial reagent with substituted aryldimethylsilanes gave relative rate constants which showed good ...
