1-Phospha-2-azanorbornenes, the cycloaddition products of 2H-phospholes with a sulfonyl imine, can be converted to 1-phospha-bicyclo[3.2.1]octa-2,5-dienes by a reductive rearrangement. This reaction is, however, dependent on the substituent R in a-position. While a clean reaction is observed for R = H or Ph, the 2-pyridyl derivative leads to a complex product mixtures.
