- W278446257 abstract "Titration calorimetry has been used to determine the enthalpies of protonation (AHHM) of the iridium in the Cp'Ir(l,5COD) (Cp' = CsMexHs-x, x = 0, 1, 3-5) complexes according to the reactions. Cp'Ir(l,5-COD) + CF3SO3H (0.1 M) -> [Cp'Ir( 1,5C0D)]+CF3S03-, at 25.0 ®C in 1,2-dichloroethane, The AHHM values become more exothermic from -22.8 ± 0.2 kcal mol-1 for Cp' = C5H5 to -28.5 ± 0.2 kcal mol'l for CgMeg. A plot of AHHM vs the number of Me groups on Cp' is linear; this result has been interpreted to indicate that the bulkiness of the Me group, even in the CgMeg ligand probably does not affect the AHHM values. Each Me group contributes -1.1 kcal mol'^ to AHHMCorrelations between AHHM and the COD olefin ^H NMR chemical shift of the protonated species are also made. Equilibrium studies for the protonation of Cp'Ir( 1,5COD) show that the effect of each added Me group on AG® is -0.89 kcal moll and on AS® is -0.7 eu. Thus, AS® contributes little to the differences in equilibrium constants for protonation of the Cp'Ir(l,5COD) complexes. A comparison of the common C5H5 and CgMeg ligands shows that the replacement of C5H5 by CgMeg increases the equilibrium constant for the protonation of Cp'Ir( 1,5-COD) by 1900, makes AG® more favorable by -4.5 kcal mol-1, causes AHHM to be more exothermic by -5.7 kcal mol'^, and reduces AS® slightly by —4 eu." @default.
