Studies of the bromine-silver carbonate reaction with aliphatic alcohols in which intramoleular δ-H competition is possible are generally quite specific. Loss of tertiary δ- hydrogen occurs preferentially from both tertiary and secondary alfphatic alcohols to yield the most highly substituted cyclic ether. For example, 2,5-dimethyl-2-octanol yields only 2,2,5-trimethyl-5-propyletrahydrofuran as the
溴-碳酸银与脂肪族醇的反应的研究通常是非常具体的,在脂肪族醇中可能发生分子内δ-H竞争。叔-仲醇和叔-仲醇均优先损失δ-氢,从而生成取代度最高的环醚。例如,2,5-二甲基-2-辛醇仅产生2,2,5-三甲基-5-丙基四氢呋喃作为环醚产物;未检测到2-甲基-2-异戊基四氢呋喃。
