Abstract
Abstract The borane adducts of 3-fluoro-, 3- and 4-chloro-, 3- and 4-bromo-, and 3- and 4-cyanopyridine were prepared and characterized by chemical analyses, 1 H and 11 B NMR spectroscopy, IR, and differential scanning calorimetry. The 4-halopyridines as well as the two cyanopyridine derivatives were found upon heating to exhibit exothermic transtions, in contrast to the endothermic transitions of the 3-substituted pyridineboranes.
