化合物简介
Diphenylphosphine oxide is an organophosphorus compound with the formula (C6H5)2P(O)H. It is a white solid that soluble in polar organic solvents. The compound is used in Buchwald-Hartwig coupling reactions to introduce a diphenylphosphino substituent. Analogous to the behavior of phosphorous acid, diphenylphosphine oxide exists in equilibrium with a minor tautomer hydroxydiphenylphosphine (CAS#24630-80-6) (C6H5)2POH.

用途
二苯基氧膦[Ph2P(O)H]常用于制备三苯基氧膦 、烯基二苯基氧膦 、与炔烃的加成 和Wittig-Horner反应试剂 。 二苯基膦衍生物的合成 Ph2P(O)H和三氟甲磺酸芳基酯偶合,膦氧化物经还原得到二苯基芳基膦 (
式1) ,是常用的手性配体。 Ph2P(O)H和TMSCl反应得到三甲基硅氧基二苯基膦,它与卤代烯烃发生反应得烯基二苯基氧膦 (
式2) 。 与炔烃的加成 在金属催化下,二苯基氧膦与炔烃加成可生成高度立体专一的烯烃化合物 (
式3) 。 与烯烃的加成 在微波条件下,二苯基氧膦与烯烃能够发生加成反应,反应不需要任何溶剂和催化剂 (
式4) 。 与二氟一氯甲烷的反应 Ph2P(O)H与二氟二氯甲烷反应可制备二氟甲基二苯基氧膦,它进一步与醛或酮反应生成1,1-二氟代烯烃 (
式5) 。
