Notes:
T1 values for the protonated carbons of four acyl compounds, all possible combinations of methylpropanoyl and 2-ethylbutanoyl groups with cyclopentadienyl- and methylcyclopentadienyl-iron dicarbonyl, were determined at ambient temperature. Carbon-13 T1 ratios for the acyl group relative to the ring system indicate relative differences in motion when obtained in the two solvents, CDCl3 and CD2Cl2. T1 values at -10°C, relative to 24°C, give further insight into motional modes. Carbon-13 and proton NMR chemical shift values for all compounds and the NOE for one compound are reported.
