Cycloaddn. of the title compds. I (R = Ph, 4-MeOC6H4) with diphenylisobenzofuran gave 1:1 adducts II resulting from cycloaddn. of the cyclopropene bridge bond rather than the exocyclic olefin. The results are in accord with computational data. The structure of II (R = Ph) was proved by x-ray crystallog.
