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).

Alkyl, hydride, carbonyl, phosphine, and pi ligands are discussed in some detail, followed by oxidative addition, reductive elimination, insertion and elimination, and addition and abstraction reactions.
Hydrogen abstraction reactions were found to be relatively slow at lower temperatures in poor hydrogen donating solvents.
Upon demonstrating that it is possible to grow phase-pure nanocrystalline diamond without the mediation of atomic hydrogen abstraction reactions, it was confirmed that many of the undesirable properties of diamond films grown by chemical vapor deposition are by-products of atomic hydrogen and do not represent intrinsic properties of thin diamond films.
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.
