ethers, and aryl groups were employed. The corresponding aminotroponiminate zinc complexes were then synthesized and characterized by a number of techniques, including by X-ray crystallography. Herein we report on the investigations into their activity in the intramolecular hydroamination of nonactivated alkenes. We also demonstrate that complexes bearing ligands with cyclic alkyl groups show superior
已经制备了一系列对称和不对称的N,N′-二取代的氨基troponimines(ATIHs)。使用从直链至环状烷基,螯合醚和芳基的取代基。然后,通过多种技术,包括通过X射线晶体学,合成并表征了相应的氨基troponiminate锌配合物。在此,我们报告了对它们在未活化烯烃的分子内加氢胺化中的活性的研究。我们还证明了带有环烷基配体的配合物在许多与官能化的氨基烯烃的选定反应中显示出优异的活性。
