Excited- and Ground-State Versions of the Tri-.pi.-methane Rearrangement: Mechanistic and Exploratory Organic Photochemistry.

Original language description

The di--methane rearrangement with two -groups bonded to a single carbon leading to -substituted cyclopropanes is now well established. The present research had as its goal the exploration of molecular systems having three -moieties attached to an sp3-hybridized atom in a search for a tri--methane rearrangement. Indeed, it was found that such systems do rearrange photochemically to afford cyclopentenes. However, it was also established that vinylcyclopropanes ring-expand to cyclopentenes on direct irradiation. Since both three-ring and five-ring photoproducts often are found to be produced, it was important to establish that the observed photochemistry was really the result of a true single-step tri--methane rearrangement and not the consequence of twosequential rearrangements, first to form a vinyl cyclopropane which subsequently ring expanded to the cyclopentene. The general situation has three species-A, B, and C-corresponding to tri--methane reactant A, vinylcyclopropane photoprod
