Abstract

The catalytic performance of salicylaldimine-based ruthenium carbonyl complexes [ArN = CH(3-^tBuC₆H₃O)]₂Ru(CO)₂ [Ar = C₆H₅ (1a); 4-OMeC₆H₄ (1b); 4-MeC₆H₄ (1c); 2,4,6-Me₃C₆H₂ (1d); 4-ClC₆H₄ (1e); 4-BrC₆H₄ (1f)] were explored in aerobic oxidation of aromatic amines to amides in refluxing ^tBuOH. All the ruthenium complexes 1a-1f showed good catalytic activity to selectivity access to amines and the complex 1f was found to the best catalyst. The present catalytic system is operationally simple and displayed good functional group tolerance. A variety of amides were obtained in 47 %–90 % yields.

钌（II）配合物催化伯胺以空气为氧化剂直接氧化成酰胺

水杨醛氨基钌羰基配合物[ArN = CH(3- tbuc6h30)]2Ru(CO)2 [Ar = C6H5 (1a)]的催化性能4-OMeC6H4 (1 b);4-MeC6H4 (1 c);2、4、6-Me3C6H2 (1 d);4-ClC6H4 (1 e);探讨了4-BrC6H4 (1f)]在回流丁醇条件下芳香族胺的好氧氧化制酰胺反应。所有钌配合物1a-1f对胺的选择性接近都表现出良好的催化活性，其中配合物1f是最好的催化剂。该催化体系操作简单，具有良好的官能团耐受性。以47% - 90%的收率得到了多种酰胺。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
