对氯苯乙酸乙酯 | 4-chloro-benzeneacetic acid, ethyl ester | 14062-24-9 | C10H11ClO2 | 198.649 |
2-p-Chlorophenyl-1-butanol (V) has been synthesized by the condensation of p-chlorophenacyl chloride (I) with ethylmagnesium chloride and dehydrochlorination of the resulting 1-chloro-2-p-chlorophenyl-2-butanol (II) to 2-ethyl-2-p-chlorophenyloxirane (III), followed by reduction. It has been discovered that reduction of III with lithium aluminium hydride yielded the tertiary alcohol, 2-p-chlorophenyl-2-butanol (IV), while reduction of III with aluminium hydride yielded the primary alcohol V. The two alcohols IV and V were also prepared by unambiguous methods. Attempts to synthesize the higher homologues of the alcohol V were not very successful.
