The stable 7-phosphanorbornadiene derivative, 2,3-benzo-1,4,5,6,7-pentaphenyl-7-phosphabicyclo[2.2.1]hepta-2,5-diene-7-oxide (1) was synthesized in 45% yield via the Diels-Alder reaction of pentaphenylphosphole oxide and benzyne. The reaction occurs specifically to give a single isomer, which was ch
The radical cation of bicyclo[2.2.l]hepta-2,5-diene (8,9,10-trinorboma-2,5-diene; 1) in CF,CICFCl, and CF,CCl, matrices and that of bicyclo[2.2.2]octa-2,5-diene (2,3-dihydrobarrelene; 2) in CFC1, and CF,CCl, matrices have been studied by ESR and'ENDOR spectroscopy. For It, the coupling constants of
