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.
该发明涉及一种制备具有以下
化学结构的化合物的过程:其中Ar-H是被激活以进行亲电攻击的芳香族化合物,而--Y是具有易失性基团的脂肪族基团,特别是易失性基团是末端不饱和基团:--C.tbd.CH,或者以他们的
缩醛的形式。该过程包括反应Ar-H和其中--X是--Cl或--Br的反应步骤,在溶剂介质中在约-40摄氏度至约-100摄氏度的温度下使用
氯化锡作为催化剂进行反应。
