A convenient and clean route to transform, in aqueous medium, various alkanes to carboxylic acids via single-pot carboxylation with CO and water, under mild conditions, has been achieved, proceeding efficiently and selectively even without any metal catalyst and any acid additive, at low temperatures; the relevant hydroxylating role of H(2)O and radical mechanisms are disclosed by radical-trap, H(2)(18)O and DFT studies.
已经实现了一种便捷且清洁的途径，即在水介质中，通过与一氧化碳和水进行单锅羧化反应，在温和条件下将各种烷烃转化为羧酸。即使在低温下，无需任何金属催化剂和任何酸添加剂，该反应也能高效且选择性地进行；通过自由基捕获、H₂¹⁸O和密度泛函理论（DFT）研究揭示了H₂O的相关羟基化作用和自由基机理。
