Palladium-catalyzed C(sp3)–P(III) bond formation reaction for alkyl substituted phosphines preparation was developed. In this reaction, various alkyl bromides and limited alkyl chlorides 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
开发了钯催化的C(sp 3)–P(III)键形成烷基取代的膦的制备反应。在该反应中,各种烷基溴化物和有限的烷基氯化物在相对温和且易于获得的条件下与酰基膦反应,并以高收率获得了不同的膦。该反应弥补了钯催化在C(sp 3)–P(III)键形成中的应用,并表明了酰基膦作为磷化试剂的实际应用。
