P'-dioxides, [Ph(2)P(O)CH(2)](2)C(6)H(2)(R)OH, with R = H (2a), Br (2b), Me (2c), (t)Bu (2d), were prepared via Arbusov reactions between Ph(2)POEt and the phenol derivatives (ClCH(2))(2)C(6)H(2)(R)OH. The compounds have been characterized by spectroscopic methods, and their coordination chemistry with lanthanide nitrates, Ln(NO(3))(3), has been surveyed. The 1:1 complexes [Er(2c)(NO(3))(3)].Me(2)CO and [Nd(2d)(NO(3))(3)
2,6-双(二苯基膦甲基)苯酚-P,P'-二氧化物[Ph(2)P(O)CH(2)](2)C(6)H(2)(R)OH,R = H(2a),Br(2b),Me(2c),(t)Bu(2d)是通过Ph(2)POEt与酚衍生物(ClCH(2))(2)C( 6)H(2)(R)OH。该化合物已通过光谱方法进行了表征,并已调查了它们与硝酸镧系元素Ln(NO(3))(3)的配位化学。1:1配合物[Er(2c)(NO(3))(3)]。Me(2)CO和[Nd(2d)(NO(3))(3).Me(2)CO] .Me (2)CO已通过单晶X射线衍射法进行了结构表征,发现该配体起中性三齿螯合物的作用。没有发现形成2:1 L:M络合物的证据,表明这些2的衍生物比相关的2,6-双(二苯基膦基甲基)吡啶N,P,P'-三氧化物螯合物更弱。
