摘要
采用1，2-二氯乙烷既作溶剂，又作烃化剂，50％NaOH作碱，经相转移反应，一步制得定量收率产物，产品纯度高，无需重结晶。
The quatitative yield of β-chloroethyl-3-o-estrone ether could be afforded by one step using phase transfer reaction in which the 1, 2-dichloroethane was used as solvent and reagent of alkylation. The product was unnecessary to recrystallize.
