Palladium-catalyzed C(sp3)–P(III) bond formation reaction for alkyl substituted phosphines preparation was developed. In this reaction, various alkyl bromides and limited alkylchlorides reacted with acylphosphine under relative mild and easily accessible condition, and differential phosphines were afforded in good yields. This reaction made up the application of palladium catalysis in C(sp3)–P(III) bond formation
Et3B-catalysed addition of diphenylphosphine oxide to unsaturatedcompounds, alkenes, unsaturated acids, allylic alcohols, and allylic α-O-acetyl nitriles constitutes a practical route to a variety of functionalized diphenylphosphine oxides. The very mild conditions employed, together with the short reaction times, make the procedure highly versatile and tolerant to a range of functionalities.
Et 3 B催化的二苯膦氧化物加成至不饱和化合物,烯烃,不饱和酸,烯丙基醇和烯丙基α- O-乙酰基腈构成了各种官能化的二苯基膦氧化物的实用途径。所采用的非常温和的条件以及较短的反应时间使该方法具有高度的通用性,并能耐受多种功能。
