A general approach to the direct deoxygenative transformation of primary, secondary, and tertiary alcohols has been developed. It proceeds through phosphoranyl radical intermediates generated by the addition of exogenous iodine radical to trivalent alkoxylphosphanes. Since these alkoxylphosphanes are readily in situ obtained from alcohols and commercially available, inexpensive chlorodiphenylphosphine
已经开发出伯醇、仲醇和叔醇直接脱氧转化的通用方法。它通过将外源碘自由基加成到三价烷氧基膦上而生成正膦基中间体来进行。由于这些烷氧基膦很容易从醇和市售廉价的氯二苯基膦原位获得,因此可以利用具有各种官能团的各种醇与烯烃或芳基碘化物进行脱氧交叉偶联。该方法还证明了多羟基底物的选择性转化和复杂有机分子的快速合成。
