  摘要：

  A procedure has been developed for the synthesis of N-cyclopentadienyl amidinium ylides of the general formula C-5(CO2Me)(4)[ArNC(Ar)NHAr]. According to the X-ray diffraction data, H-1 and C-13 NMR spectroscopy, and MNDO quantum-chemical calculations, the title compounds have a zwitterionic structure with the positive charge localized over the amidine N-C-N triad, and the negative charge, over the cyclopentadiene fragment. The configuration of the amidine moiety is stabilized by additional interaction of the NH hydrogen atom with the negatively charged cyclopentadiene ring (pi-bonding). The ylides are chiral due to atropoisomerism arising from a high energy barrier (DeltaG(298)(not equal) > 25 kcal/mol) to rotation of the Ar' substituent about the ordinary C-C bond in the amidinium fragment.

  The reaction between amines and carboxylic aicds in the presence of polyphosphoric acid trimethylsilyl ester (PPSE) has been investigated from the view point of the synthesis of amides and amidines. Benzanilide was selectively prepared from benzoic acid and aniline in the presence of PPSE and pyridine at 100 °C, whereas a mixture of benzanilide and N,N′-diphenylbenzamidine was obtained without the

  从合成酰胺和脒的角度研究了胺和羧酸在多磷酸三甲基甲硅烷基酯（PPSE）存在下的反应。在 PPSE 和吡啶的存在下，在 100°C 下，苯甲酸和苯胺有选择地制备苯甲酰苯胺，而在不使用吡啶的情况下获得苯甲酰苯胺和 N,N'-二苯基苯甲脒的混合物。在 160 °C 下的反应几乎完全得到 N,N'-二苯基苯甲脒。通过简单地在 160 °C 下与四摩尔量的 PPSE 加热，可以从羧酸和芳香胺的组合中以高产率获得各种对称脒。在相同条件下，脂肪族和芳香族胺与 N-单取代和 N,N-二取代酰胺的反应也得到相应的不对称脒。

  A robust protocol for the CuI-catalysed arylation of amidines is presented. Whilst the initially identified conditions were useful for benzamidine-derived substrates, difficulties were encountered with more complex substrates. This problem was overcome following a change in ligand type, enabling the synthesis of analogues of the chemical tool, blebbistatin.

  excellent catalytic activity for the addition of amines to carbodiimides, yielding the corresponding guanidines. Isolation, structural characterization, and catalytic application of the binuclear lutetium amido complex showed clearly that the catalytic cycle was initiated by the dissociation of Cp′. These results demonstrated that Cp′, for the first time, acted as a reactive site to yield the active Ln–N
