The substitution pattern of the 2-phosphabicyclo[2.2.2]octene framework and the skeleton itself were varied to obtain new cycloadducts usable in phosphorylations and to study their ability to undergo fragmentation. Thus, an N-methyl and several P-trialkylphenyl derivatives (7 and 9, respectively) were synthesized, together with two diaza species (8) whose stereostructure was evaluated by single crystal X-ray analysis. Mechanistic studies on the UV light-mediated photolysis of the P-aryl phosphabicyclooctenes (9) in the presence of methanol supports the suggestion of a novel addition-elimination reaction path.
