Gragg, B. R. published the artcileA carbon-13 NMR study on some phenylborane derivatives, SDS of cas: 971-66-4, the publication is Journal of Organometallic Chemistry (1977), 132(1), 29-36, database is CAplus.
The intensity of 13C NMR signals of C atoms bonded to B can frequently be increased by recording the spectra at low temperatures Though this procedure results in a loss of fine structure, it enables the determination of chem. shift data for NMR signals that are either broad or unobservable at ambient temperature High temperature recording of spectra seems to be a useful technique for resolving multiplet resonance signals that are collapsed in ambient temperature spectra. 13C NMR data are reported for a variety of phenylborane derivatives; no simple correlation seems to exist between δ13C of the phenyl C atom bonded to B and δ11B of the phenylborane species.
Journal of Organometallic Chemistry published new progress about 971-66-4. 971-66-4 belongs to pyridine-derivatives, auxiliary class Pyridine,Benzene, name is Triphenyl(pyridin-1-ium-1-yl)borate, and the molecular formula is C23H20BN, SDS of cas: 971-66-4.
