Abstract

Variable temperature NMR and EPR spectroscopic studies provide rates and activation parameters for alkyne rotation and oscillation, respectively, in the fluxional redox pair [Mo{P(OMe)3}2(MeC[triple bond, length as m-dash]CMe)Cp][BF4] (diamagnetic) and [Mo{P(OMe)3}2(MeC[triple bond, length as m-dash]CMe)Cp] (paramagnetic).
