Figure 1. Illustrations of scenarios I–III with the axial triflate as the major species and equatorial triflate as the minor species. In scenario I, product formation originates from the main reaction ...

We describe DFT computations that address the regioselective preference toward the five-membered ring product 1,3-dioxolane (solketal) over the six-membered-ring product (1,3-dioxane) during ...
