Reaction pathways operative when pyridinophane N-oxides are photoirradiated have been studied using time course analyses and careful isolation of photolabile intermediates with support from DFT calculations. Based on the data and the isolation of two previously unknown heterocyclophanes, we outline a unified mechanistic scheme that explains competing processes under varying photochemical conditions
