Abstract
(2-Pyridylamino)diethylborane has been obtained in good yield and purity by the reaction of triethylborane with 2-aminopyridine in 2 1 molar ratio in the absence of solvent. Carbon-13 NMR data suggest that at room temperature and below the compound exists in at least two forms; only at higher temperatures does the normal aminoborane form become exclusive. Pyrolysis of the compound leads to the formation of B-triethyl- N-tri-2-pyridylborazine, [BC 2H 5N(2-CHN)] 3.
