[BH3C(NO2)3]-: The First Room-Temperature Stable (Trinitromethyl)borate.
Journal article, 2013
The first stable (trinitromethyl)borate anion [BH3C(NO2)3]- was synthesized and structurally characterized. The BH3 group in [BH3C(NO2)3]- provides a significant increase in stability compared to the previously studied BCl3 analog. The [Na(glyme)2]+, PNP+, and PPh4+ salts of [BH3C(NO2)3]- were successfully isolated and characterized by NMR and vibrational spectroscopy. The PNP+ salt was structurally characterized, confirming the theor. predicted B-C connectivity. [on SciFinder(R)]
