Nucleophilic recyclization of pyridinium salts involving a CCN interchange ring transformation for the synthesis of 2-methylnicotinonitrile derivatives was herein developed. 3-Aminocrotononitrile (3-ACN) produced in situ from CH3CN acted as a C-nucleophile, as well as the source of CH3 and CN groups, which was supported by isotope-labeling and control experiments In the experimental materials used by the author, we found Pyridin-3-ylboronic acid(cas: 1692-25-7Reference of Pyridin-3-ylboronic acid)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Reference of Pyridin-3-ylboronic acid
