developed based on readily available 2-phenoxyethyldiphenylphosphine oxide used as an equivalent of diphenylvinylphosphine oxide in the reactions of addition of different PH- and NH-nucleophiles in DMSO in the presence of KOH. The transformations of labile phosphine oxides of a general formula Ph2P(O)CH2CH2OR, where R = Ph, H, or Ph2P(O)CH = CH2, in aq.KOH/DMSO and solid KOH/DMSO systems are explored
摘要 基于容易获得的 2-苯氧基乙基二苯基氧化膦,在 KOH 存在下,在 DMSO 中添加不同的 PH-和 NH-亲核试剂的反应中,作为二苯基乙烯基氧化膦的当量,开发了一种合成 β-官能化乙基二苯基氧化膦的简便方法。通式 Ph 2 P(O)CH 2 CH 2 OR的不稳定氧化膦在 aq.KOH/DMSO 和固体 KOH 中的转化,其中 R = Ph、H 或 Ph 2 P(O)CH = CH 2 /DMSO 系统是在没有亲核试剂的情况下进行的。
