摘要

The energy balance of an elementary step in a chemical transformation is fundamental to our understanding of reaction pathways. Here we evaluate the enthalpic coupling between bond cleavage and bond formation in diverse elementary steps in organic chemistry. To illustrate the relationship between specific bond-altering events, we use enthalpic maps. This analysis compares mechanistically distinct reactions and offers a framework for modifying the existing elementary steps with the objective of reaction discovery.
