H-phosphinates and related compounds was examined. A practical catalytic process with the air as the oxidant could not be found. However, an inexpensive and robust methodology was developed, using catalytic Mn(II) as the radical initiator and excess Mn(IV) as the stoichiometric oxidant. Using these conditions, the inter- and intramolecular arylation of phosphinylidene compounds has a broad scope, including
检查了H-次膦酸酯和相关化合物的自由基芳基化。找不到以空气为氧化剂的实际催化方法。但是,开发了一种廉价而稳健的方法,使用了催化性的Mn(II)作为自由基引发剂,而过量的Mn(IV)作为化学计量的氧化剂。使用这些条件,次膦基化合物的分子间和分子内芳基化具有广泛的范围,包括应用于合成P-杂环。完整介绍了该方法,并讨论了其局限性。
