摘要

In seeking to extend the generality of this reaction, the condensations of cresol with benzotrichloride4 and substituted benzotrichl~ rides~ were studied. Although these reactions led to the formation of several new substances, no compounds analogous to I were isolated. We now show that the condensation of p-cresol and of other phenols with hexachloropropene in the presence of aluminum chloride yields 3, 4-dichlorocoumarins. ...
