✦ Synopsis

Abstract

The Friedel–Crafts reaction of P‐substituted 6,6‐dichloro‐3‐phosphabicyclo [3.1.0] hexane 3‐oxides with benzene derivarives yields selectively new tricyclic benzophosphabicyclooctenes. The relative configuration and conformation of these products were elucidated by various ^1^H and ^13^C NMR methods.
