ABSTRACT:
The present invention involves process for the preparation of compounds having the chemical structure: ##STR1## wherein Ar--H is an aromatic compound which is activated to an electrophilic attack, and wherein --Y is an aliphatic group having a labile moiety, especially where the labile moiety is a terminally unsaturated moiety: --C.tbd.CH, ##STR2## or aldehydes in the form of their acetals. The process comprises the step of reacting Ar--H and ##STR3## wherein --X is --Cl or --Br, and where the reaction step is carried out in a solvent medium at a temperature of from about -40.degree. C. to about -100.degree. C. using stannic chloride as a catalyst.
