  摘要：

  2-苄氧基苯乙烯在-78°C下经历有效的羰基化质子化反应。然而，在更高的温度下，碳酸酯化之后是分子内烷基化以生成相应的2-烷基苯酚。显示2-环氧苯乙烯经历类似的反应。

  2-Benzyloxystyrene undergoes efficient carbolithiation-protonation at −78°C. At higher temperatures, however, carbolithiation is followed by intramolecular alkylation to generate the corresponding 2-alkylphenol. 2-Alloxystyrenes are shown to undergo similar reactions.
