The reactions between tetrabutylammoniumborohydride and a series of nitrogen-containing heteroaromatics bases have been investigated by electron paramagnetic resonance (EPR) spectroscopy. The radical anions of the N-heterocycles, formed by a single electron-transfer process have been observed with substrates having reduction potentials higher than - 1.2 V vs. SCE. With less reducible bases, the radical
