Sustainable Synthetic Approach for (Pyrazol-4-ylidene)pyridines By Metal Catalyst-Free Aerobic C(sp(2))–C(sp(3)) Coupling Reactions between 1-Amino-2-imino-pyridines and 1-Aryl-5-pyrazolones
[Image: see text] A novel, metal catalyst-free, and efficient method has been developed for the synthesis of (pyrazol-4-ylidene)pyridine derivatives. The process involves dehydrogenative coupling of 1-amino-2-imino-pyridines with 1-aryl-5-pyrazolone derivatives utilizing O(2) as the sole oxidant. Th...
