Base-metal catalysts Co1, Co2 and Co3 were synthesized from designed pincer ligands L1, L2 and L3 having NNN donor atoms, resp. Co1, Co2 and Co3 were characterized by IR, UV-visible and ESI-MS spectroscopic studies. Single crystal x-ray diffraction studies were studied to authenticate the mol. structures of Co1 and Co3. Catalysts Co1, Co2 and Co3 were used to study the dehydrogenative activation of alcs. for N-alkylation of amines, α-alkylation of ketones and synthesis of quinolines. Under optimized reaction conditions, a broad range of substrates including alcs., anilines and ketones were exploited. Control experiments for N-alkylation of amines, α-alkylation of ketones and synthesis of quinolines were examined to understand the reaction pathway. ESI-MS spectral studies were studied to characterize Co-alkoxide and Co-hydride intermediates. Reduction of styrene by evolved H gas during the reaction was studied to authenticate the dehydrogenative nature of the catalysts. Probable reaction pathways are proposed for N-alkylation of amines, α-alkylation of ketones and synthesis of quinolines from control experiments and detection of reaction intermediates. In the experimental materials used by the author, we found 4-Acetylpyridine(cas: 1122-54-9Related Products of 1122-54-9)
4-Acetylpyridine(cas: 1122-54-9) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Related Products of 1122-54-9
