摘要：

The phase-transfer catalyzed beta-elimination of HBr from alkyl bromides with aqueous NaOH in two-phase systems proceeds efficiently when tetraalkylammonium salts and weak HO- or HN-acids are used as the catalysts. The latter continuously produce basic, moderately nucleophilic, lipophilic anions, which in the form of tetraalkylammonium salts afford the elimination in the organic phase.
