✦ Synopsis

The relative quantum efficiencies of allylphosphonate (%12) formation, from the triplet-sensitized photoresrrangement of allyl phosphites (1-6), can be qualitatively correlated using the 1.2-b'wadical model for ~-g* excited states and considering the effect on excited state energies and lifetimes of placing the bond in a small ring.

Structure-reactivity relationships in photoreactio;s are of great interest and importance. 1 Previously 0-acyloximes of aromatic ketones were shown to undergo homolytic cleavage at the N-O bond on excitation to their triplet states. 2 We now wish to report on studies designed to determine structura
