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 characterized by use of X-ray crystallography and 31P NMR spectroscopy. © 2000 John Wiley & Sons, Inc.
