摘要：

Rh-103 chemical shifts of (eta(5)-C5H4X)Rh(CO)2 complexes (X = H, CH3, N(CH3)2, CF3. Cl, NO2) show a linear correlation (R2 = 0.973) with rate constants log k(obsd) of the CO/PPh3 displacement reaction reported by Basolo and Cheong. Increasing reactivity is reflected in lower shielding of the Rh-103 nucleus, and substituents with lone-pair electrons (N(CH3)2, Cl) do not disturb the correlation.
