So, it is concluded that although the aromatic tertiary amine has reactivity and supply hydrogen atoms to hydrogen abstraction reaction
of carbonyl, the aliphatic tertiary amine is more reactive and makes an important role in hydrogen abstraction reaction
Moreover, it was assumed that reactions most likely proceed via saddle point transition state structures than via other thermodynamically less favorable reaction paths; consequently, for example, the hydrogen abstraction reaction
rate magnitude is anticipated to proceed in the following order: allylic > tertiary > secondary > primary > vinylic (3).
Hydrogen abstraction reactions
were found to be relatively slow at lower temperatures in poor hydrogen donating solvents.
Temelso conducted all of the research and a majority of the writing of an article which systematically examines hydrogen abstraction reactions
of interest to mechanosynthesis using very accurate, state-of-the-art quantum mechanical models.
