✦ Synopsis
A spiro attack on a peroxo group is calculated to be the preferred reaction pathway for olefin epoxidation with the catalytic system CH ReO /H O (see picture). This finding is supported by density functional calculations on more than ten transition states for the most probable mechanisms. Hydration has significant effects on various reaction species: it stabilizes the intermediates and destabilizes, with one exception, the transition states.

The mechanism of copper(I)-catalyzed olefin cyclopropanation with diazomethanes has been studied at the BP86/AE1 level of density-functional theory. For the model system Cu(diazabutadiene) + + ethene + diazomethane, copper carbene complexes are confirmed as viable intermediates, with rate-determinin
