Uranium-ligand bond disruption enthalpies have been obtained by application of iodinolysis batch-titration solution calorimetry to the (C 9 H 7 ) 3 U/(C 9 H 7 ) 3 U-I/(C 9 H 7 ) 3 U-CH 3 system. Derived values in toluene solution are as follows: (C 9 H 7 ) 3 U-I, 266.8 ± 3.2 kJ mol −1 ; (C 9 H 7 ) 3 U-CH 3 , 196.3 ± 6.6 kJ mol −1 . The correlation between the latter value and that obtained recently by alcoholysis confirms that the value of D (U-I) is certainly a better parameter for placing D data on an absolute scale than D (U-O). |
