[Kinetics and mechanism of oxygen atom transfer reactions between iron (II) isocyanide complexes and (CH3)3NO].
Kinetics and mechanism of reactions between iron (II) isocyanide complexes [FeL5 (CN)] Br (1, L = -CNCH2Ph); trans- [FeL4 (CN)2] 2, L = -CNCH2Ph) and oxygen atom transfer agent (CH3)3NO have been investigated in dichloromethane by UV-visible and Infrared spectrophotometers at different temperatures. The results revealed that the reactions proceed with second order and the rate law is rate = k2 [isocyanide complex] x [(CH3)3NO]. delta S not equal to and delta H not equal to for the reaction between complex 1 and (CH3)3NO are -25.34 +/- 1.67 cal.(mol.K)-1 and 12.71 +/- 0.49 kcal.mol-1 respectively. However, there is no reaction between 2 and (CH3)3NO. The reaction mechanism was proposed and the factors affecting the reaction rate were also discussed.
