👉 Tautomerization, also known as homotactic substitution or homotopy elimination, is a process in chemistry that involves replacing one compound with another by using the same set of atoms. This can be useful for creating new compounds, altering existing ones, and improving their properties. In tautomerization, two molecules are combined to form one molecule that contains only the desired chemical property (tautomeric transformation). The goal is to achieve this transformation without changing the original structure or reaction mechanism.
