A wide range of benzyl carbonates reacted with dimethyl phosphonate or diphenylphosphine oxide in the presence of the palladium catalyst, [Pd(η3-allyl)Cl]2–DPEphos, to give dimethyl benzylphosphonates and benzyldiphenylphosphine oxides in high yields. The catalytic phosphonylation was applied to the one-pot synthesis of alkenes from the benzyl esters.
在钯催化剂 [Pd(η3-烯丙基)Cl]2-DPEphos 存在下,各种碳酸苄酯与膦酸二甲酯或氧化二苯基膦反应,以高产率得到苄基膦酸二甲酯和苄基二苯基氧化膦。催化膦酰化应用于从苄酯合成烯烃的一锅法。
