(2009-05-15)A variety of biological and organic reaction mechanisms are studied using powerful tools from experimental and theoretical chemistry. These tools include the precise measurement of kinetic isotope effects (KIEs) and the ...
-
(2022-09-27)Reaction mechanisms are generally probed by looking at the energetics of observable intermediates and the transition states that have observable effects on rates or selectivity. Mechanisms are complex, however, and there ...

(2011-10-21)The [2,3]-sigmatropic rearrangement is a pericyclic reaction of great synthetic utility to organic chemists. Within the scope of this reaction exist some cases in which the product corresponding to a [1,2] rearrangement ...
-
(2009-05-15)Detailed mechanistic studies were conducted on several organic reactions that exhibit product selectivity (regio-, peri-, or enantioselectivity). The organic reactions studied were electrophilic aromatic substitutions, ...
-
(2021-07-08)Pericyclic reactions generally occur through a single concerted transition state where all bonds are being formed and broken in a synchronous fashion. Previous experimental observations in the singlet oxygen (1Δg) ene ...

(2017-06-26)Statistical models, like Transition State Theory (TST), are used in order to predict rates and selectivities of reactions. However, these models often fail to explain experimental results. In such cases, consideration of ...
