Abstract
The stable 7-phosphanorbornadiene derivative, 2,3-benzo-1,4,5,6,7-pentaphen yl-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 benz yne. The reaction occurs specifically to give a single isomer, which was ch aracterized by use of X-ray crystallography and P-31 NMR spectroscopy. (C) 2000 John Wiley & Sons, Inc.
