我们已经知道 P-H 键的磷化物加到羰基化合物上可得到在其α-碳原子上具有羟基的磷化物,虽然羟基直接变为氢从未成功,然而,由亚硫酰氯将其转变为氯也只有醛加合物。即1-羟基乙磷酸二乙酯是成功的。这个报告叙述了(1-羟基乙基)二苯基膦化氧和它的同系物与四碘化二磷的反应。为了直接制备相应的伯、仲二苯基膦化氧的烷 We have already known that the phosphine bond of the PH bond to the carbonyl compound results in a phosphide having a hydroxyl group on its alpha-carbon atom. Although the hydroxyl group has never been directly converted to hydrogen, however, conversion from thionyl chloride to chlorine also Only aldehyde adduct. Diethyl 1-hydroxyethyl phosphate is successful. This report describes the reaction of (1-hydroxyethyl) diphenylphosphine oxide and its homologues with diphosphonium tetraiodide. In order to directly prepare the corresponding primary, secondary diphenyl phosphine oxide
