halogen-free synthesis of functional triphosphines with nitrogen and (or) oxygen atoms as additional weaker coordinating sites (new hemilabile ligands) through exhaustive addition of secondary phosphines to available trivinyl ethers of aminotriols and triols has been developed. The reaction proceeds under free-radical conditions (UV irradiation or AIBN, with 3:1 reactant molar ratio) to give chemo- and
摘要 通过将仲膦穷尽地添加到氨基三醇的三乙烯基醚中,将一氧化氮与(和)氧原子作为其他较弱的配位位点(新的半不稳定配体)进行一锅,无原子经济,无金属和卤素的合成已开发出三醇。反应在自由基条件下进行(UV辐射或AIBN,反应物摩尔比为3:1),从而以良好或优异的收率为所有三个乙烯基氧基提供化学和区域选择性的反马尔科夫尼科夫三加合物。 通过将仲膦穷尽地添加到氨基三醇的三乙烯基醚中,将一氧化氮与(和)氧原子作为其他较弱的配位位点(新的半不稳定配体)进行一锅,无原子经济,无金属和卤素的合成已开发出三醇。反应在自由基条件下进行(UV辐射或AIBN,反应物摩尔比为3:1),从而以良好或优异的收率为所有三个乙烯基氧基提供化学和区域选择性的反马尔科夫尼科夫三加合物。
