Pw. Cyr et al., A remarkable temperature-dependent, accidental degeneracy of P-31 NMR chemical shifts in Ru(II) diphosphine/diimine complexes, CHEM COMMUN, (17), 2001, pp. 1570-1571
Several cis-RUX2((R)-BINAP)(diimine) complexes have been prepared, and many
of these exhibit an unusual temperature-dependent, accidental degeneracy o
f the P-31 shifts in their solution NMR spectra.
