The kinetics of photochemical reactions. Part IV. Photoreduction of carbonyl triplets by bonds other than C–H. Semiempirical calculations

Abstract

A modified B.E.B.O. (Bond Energy–Bond Order) method has been used to calculate kinetic parameters for the reactions of carbonyl triplets with various substrates having X–H bonds (where X is not carbon). The results are compared with experiment where this is possible. The possibility of abstraction of hydrogen atoms bonded to oxygen or nitrogen should be taken into account rather than disregarded a priori.
