Sengupta, D and Sumathi, R and Chandra, AK (1991) The Mechanism Of The Hydrogen Abstraction Process By Photo-Excited Ketones. In: New Journal of Chemistry, 15 (12). 901 -907.Full text not available from this repository.
Qualitative potential energy surfaces for hydrogen abstraction from alkanes containing primary, secondary and tertiary C-H bonds by a photo-excited ketone have been reported, The results suggest that the activation barriers for these processes decrease in the order primary > secondary > tertiary in agreement with the observed trend in the rate constants. The analysis of the electronic structure of the transition-state reveal that electron-transfer from hydrocarbon to ketone and formation of a new bond are almost synchronous in the hydrogen transfer process. The tunneling of hydrogen is not important in the normal temperature region even though the barriers are small.
