Synthesis of sodium cyanotrihydroborate and sodium isocyanotrihydroborate

Article abstract of DOI:10.1021/ic50091a036

A convenient synthetic procedure for sodium cyanotrihydroborate (NaBH₃CN) is reported. Sodium isocyanotrihydroborate has also been isolated in mixtures with the normal salt and characterized. The isomerization of NaBH₃NC to NaBH₃CN has been investigated and is found to be H⁺ and CN^- catalyzed. Boron nmr data are reported for BH₃CN^-, BH₃NC^-, and BH₃CNBH₃^-. The infrared spectra of NaBH₃NC, NaBD₃NC, and NaBH₃CNBH₃ have been recorded and the fundamental vibrations assigned and compared with those reported earlier for NaBH₃CN and NaBD₃CN.
