  高价（叔丁基过氧）碘在室温下在溶液中生成以碘为中心的自由基：苄基和烯丙基醚的氧化和脱保护，以及生成 α-氧碳自由基的证据

  摘要：

  1-(tert-Butylperoxy)-1,2-benziodoxol-3(1H)-one (1a) 在室温下，在苯或环己烷中，在碱金属碳酸盐存在下，将苄基和烯丙基醚氧化成酯。由于该反应与其他保护基团（例如 MOM、THP 和 TBDMS 醚以及乙酰氧基）相容，并且由于酯在碱性条件下容易水解，因此这种新方法为通常的还原性脱保护提供了一种方便有效的替代方法。与 1a 的氧化很容易发生，C-H 键被焓效应（苄基、烯丙基和炔丙基 C-H 键）和/或极性效应（α-氧 C-H 键）激活，生成 α-氧碳中心自由基，可以通过硝酰基自由基捕获来检测。
