  The ruthenium pyrazolonate complex Ru(PMIP)2(PPh3)2: Synthesis, structure, and some properties

  摘要：

  The new ruthenium(II) complex Ru(PMIP)(2)(PPh3)(2) (HPMIP is 4-isobutyryl-3-methyl-1-phe-nylpyrazol-5-one) was obtained from RuCl2(PPh3)(3) and Na(PMIP)(DME) (DME is dimethoxyethane). The structures of the complex obtained and the starting sodium pyrazolonate were determined by X-ray diffraction. The ruthenium pyrazolonate complex initiates metathetical norbornene polymerization producing high-molecular-weight polynorbornene in low yield.

  Novel bilirubin and biliverdin congeners with propionic acids replaced by o-carboxyphenyl exhibit diastereomerism due to axial chirality about the carbon–carbon single bond linking the o-carboxyphenyl group to a pyrrole ring. Evidence for atropisomerism was found even in the monopyrrole precursor, ethyl 3,5-dimethyl-4-(o-carboxyphenyl)pyrrole-2-carboxylate. Like bilirubin, o-carboxyphenyl rubin 1a

  丙酸被邻羧基苯取代的新型胆红素和胆绿素同系物由于将邻羧基苯基与吡咯环相连的碳-碳单键的轴向手性而表现出非对映异构性。甚至在单吡咯前体3,5-二甲基-4-（邻羧基苯基）吡咯-2-羧酸乙酯中也发现了对映异构现象。像胆红素一样，邻羧基苯基红素1a在非极性溶剂中也采用分子内氢键键合的脊-瓦构象。在含有旋光胺或人血清白蛋白1a的溶液中，由于其在400 nm附近的长波长吸收，显示出强烈的双信号激子偶联型诱导的圆二色性。
