Acid chlorides, complexed with excess aluminium chloride, reacted with ethene to form 3-methyl-2-buten-1-ones, i.e. rearranged di-addition products having a terminal isoprenoid skeleton, together with the usual β-chloropropanones. The latter were the sole products in the absence of excess catalyst. Acid chlorides containing a suitably situated π-system underwent intramolecular cyclization, e.g. 2-
酰氯与过量的氯化铝络合,与乙烯反应形成3-甲基-2-丁烯-1-酮,即具有末端类异戊二烯骨架的重排二加成产物,以及通常的β-氯丙烷。后者是在没有过量催化剂的情况下的唯一产物。含有适当位置的π系统的酰氯进行了分子内环化,例如将2-苯基环丙烷羰基氯(10)环化为3,4-苯并双环[3.1.0]己-2-酮(11)。
