Base-metal catalystsCo1,Co2andCo3were synthesized from designed pincer ligandsL1,L2andL3having NNN donor atoms respectively.Co1,Co2andCo3were characterized by IR, UV-Vis. and ESI-MS spectroscopic studies. Single crystal X-ray diffraction studies were investigated to authenticate the molecular structures ofCo1andCo3. CatalystsCo1,Co2andCo3were utilized to study the dehydrogenative activation of alcohols forN-alkylation of amines, α-alkylation of ketones and synthesis of quinolines. Under optimized reaction conditions, a broad range of substrates including alcohols, anilines and ketones were exploited. A series of control experiments forN-alkylation of amines, α-alkylation of ketones and synthesis of quinolines were examined to understand the reaction pathway. ESI-MS spectral studies were investigated to characterize cobalt-alkoxide and cobalt-hydride intermediates. Reduction of styrene by evolved hydrogen gas during the reaction was investigated to authenticate the dehydrogenative nature of the catalysts. Probable reaction pathways were proposed forN-alkylation of amines, α-alkylation of ketones and synthesis of quinolines on the basis of control experiments and detection of reaction intermediates.

Paragraph 0063-0064, (2020/12/08)
The invention discloses a preparation method of a novel aromatic ketone compound. According to the preparation method, an aromatic carboxylic acid compound and an aromatic olefin compound are used asreaction raw materials, triphenylphosphine is taken as a deoxidizing reagent, Methylenene blue is taken as a photocatalyst, stirring and reacting are carried out at room temperature in an N,N-dimethylacetamide solvent under the irradiation of a white light lamp in a nitrogen atmosphere and under the condition of taking 2,4,6-trimethylpyridine as an alkali, thereby obtaining a target product, namely the aromatic ketone compound. The method has the advantages of mild reaction conditions, simplicity in operation, low cost, convenience in purification, environmental friendliness and the like.
