The article was titled ãRhodium-Catalyzed Chemodivergent Pyridylation of Alkynes with Pyridylboronic Acidsã? and you may find the article in Organic Letters.Electric Literature of C5H6BNO2 The information in the text is summarized as follows:
The pyridylation of alkynes with pyridylboronic acids is realized under rhodium catalysis. Chemodivergent pyridylation products, including alkenylpyridines produced via the hydropyridylation pathway and cyclopenta[c]pyridines produced via the pyridylation/cyclization pathway, were selectively produced by fine-tuning the reaction conditions. A mechanistic study revealed that 1,4-rhodium migration to the pyridine ring was involved as the key step in the chemodivergent synthesis. The results came from multiple reactions, including the reaction of Pyridin-3-ylboronic acid(cas: 1692-25-7Electric Literature of C5H6BNO2)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridine is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an important reagent and organic solvent.Electric Literature of C5H6BNO2
