The double effect of ethylaluminium sesquichloride on ω-phenylcarboxylic acid chlorides with a chain length of C3 to C6, namely alkylation and Friedel-Crafts cyclization was investigated. It was established that the two alternatives are possible only with 4-phenylbutyryl chloride. Depending on the reaction conditions, both alkylation and cyclization yield 6-phenyl-3-hexanone, as well as 1-tetralone
研究了倍半氯化乙基铝对链长为C 3至C 6的ω-苯基羧酸氯化物的双重作用,即烷基化和Friedel-Crafts环化。已经确定,这两种选择仅对于4-苯基丁酰氯是可行的。取决于反应条件,烷基化和环化均产生6-苯基-3-己酮以及1-四氢萘酮。其他三种ω-苯基羧酸氯化物(C 3,C 5和C 6)仅产生相应的ω-苯基-3-链烷酮。
