Abstract

A new bis(amidate)zirconium bis(amido) hydroamination pre-catalyst using 6-tert-butyl-3-phenyl-2-pyridone as a proligand has been prepared and characterized. This rare example of an early transition metal complex incorporating a 2-pyridonate derivative as an ancillary ligand was found to be effective for the cyclohydroamination of aminoalkenes, including more challenging substrates bearing unactivated internal C=C bonds.

摘要

一种新型的双（酰胺）二锆双（酰胺）氢氨化预催化剂，使用 6-叔丁基-3-苯基-2-吡啶酮作为前配体，已经被制备和表征。这种罕见的早期过渡金属配合物，其中包含 2-吡啶酮衍生物作为辅助配体的例子，被发现对于氨基烯烃的环氢氨化反应非常有效，包括更具挑战性的含有未活化的内部 C=C 键的底物。
