  摘要：

  The present invention describes a mixture of isomeric aldimines of the formulae (Ia), (Ib) and (Ic) in which the ratio of the trans,trans isomer (Ia) to the sum of the cis,trans isomer (Ib) and the cis,cis isomer (Ic) is in the range of 5/95 to 30/70, and its use as latent hardener for moisture-curing isocyanate-functional polyurethane compositions. The inventive mixture of isomeric aldimines enables polyurethane compositions with very low content of monomeric isophorone diisocyanate and excellent stability under outdoor wheathering conditions and high UV load, which cure quickly to an elastic material of low surface tack and good mechanical properties, particularly in terms of high tensile strength and modulus of elasticity at high elongation. Such compositions are particularly suitable as elastic adhesives and/or sealants or elastic coatings, particularly for outdoor use such as on roofs, floors or ships.

  dinuclear iron carbonyl complexes show an aza-ferra-cyclopentadiene ligand which is apically coordinated by the second iron tricarbonyl moiety. Comparing the bond lengths of 43 different compounds, which were synthesized and structurally characterized in our group shows that the iron iron bond length correlates with one of the iron carbon bond lengths. The longer the iron carbon bond between the apically

  芳族亚胺与Fe 2（CO）9的反应通过两步反应顺序进行。邻位AC–H活化反应在相对于环外亚胺功能的-位置上，进行朝向前亚胺碳原子的分子内氢转移反应。所得的双核羰基铁配合物显示出氮杂-ferra-环戊二烯配体，该配体由第二三羰基铁部分配位。比较了我们合成的43种不同化合物的键长并对其结构进行了结构表征，结果表明，铁-铁键长与其中一个铁碳键长相关。顶端配位的铁原子与紧邻前一个亚胺碳原子的碳原子之间的铁碳键越长，铁-铁键越短。相同的配体可用作钌催化的CC键形成反应的底物。在亚胺官能团的邻位上，在相同反应条件下在模型化合物中显示最长铁碳键长度的配体会产生不同类型的异吲哚酮。
