TL;DR: Analysis of reactivity and mechanistic problems in organic and organometallic chemistry exemplifies the generality of the VB paradigm: in situ DNA repair, C-F and C-H bond activation, SRN 2c mechanism, stepwise versus concerted cycloaddition, and a lot more.

Abstract: A unified description of chemical reactivity is made possible with valence bond (VB) diagrams, such as those shown for the a simple case (only reactants and products must be considered) and a more complex system (an intermediate state also plays an important role; RC = reaction coordinate). Analysis of reactivity and mechanistic problems in organic and organometallic chemistry exemplifies the generality of the VB paradigm: in situ DNA repair, C-F and C-H bond activation, SRN 2c mechanism, stepwise versus concerted cycloaddition, and a lot more.

Analyzing Reaction Rates with the Distortion/Interaction‐Activation Strain Model
TL;DR: This model has been applied to reactions of all types in both organic and inorganic chemistry, including substitutions and eliminations, cycloadditions, and several types of organometallic reactions.
P450 Enzymes: Their Structure, Reactivity, and Selectivity—Modeled by QM/MM Calculations
TL;DR: This work confirms that setup issues can be resolved in a consistent manner if proper care is exercised and generates a common setup that gives QM/MM results for P450cam which are generally consistent with those obtained previously with individual setups.

A combined kinetic-quantum mechanical model for assessment of catalytic cycles: application to cross-coupling and Heck reactions.
Sebastian Kozuch and,Sason Shaik +1 more
TL;DR: A kinetic model developed by Christiansen is implemented here in a form that utilizes state energies, which enables one to assess the efficiency of quantum mechanically computed catalytic cycles like the palladium-catalyzed cross-coupling and Heck reactions, to test alternative hypotheses, and to make some predictions.

Oriented electric fields as future smart reagents in chemistry
TL;DR: It is postulate that, as experimental techniques mature, chemical syntheses may become an exercise in zapping oriented molecules with OEEFs, and the wide-ranging potential of using OEEF to catalyse and control a variety of non-redox reactions and impart selectivity at will is discussed.
