Decomposition of hydrogen peroxide with a hypervalent iodine compound was examined. The results indicate that treatment of a hypervalent iodine compound with hydrogen peroxide produces singlet molecular oxygen ((1)O(2)). Convergent evidence for the production of singlet molecular oxygen ((1)O(2)) by decomposition of hydrogen peroxide with a hypervalent iodine compound comes from chemical trapping experiments and the specific chemiluminescence detection of (1)O(2) at 1270 nm. Substantial evidence demonstrates that hydroperoxyl radical produced from hydrogen peroxide with hypervalent iodine reacts via a tetraoxidane intermediate, decomposing to give singlet molecular oxygen.
研究了用高价碘化合物分解过氧化氢的情况。结果表明,用过氧化氢处理高价碘化合物会产生单线态分子氧((1)O(2))。通过化学捕获实验以及对1270nm处(1)O(2)的特异性化学发光检测,获得了关于用高价碘化合物分解过氧化氢产生单线态分子氧((1)O(2))的趋同证据。大量证据表明,过氧化氢与高价碘反应产生的氢过氧自由基通过四氧化烷中间体发生反应,分解生成单线态分子氧。
