β¦ Synopsis
The first examples of intramolecular cation radical Die&-Alder reactions have been established using trienes which cyclize to hydroindane systems.
The extremely high endo stereoselectivity characteristic of the cation radical Diels-Alder reaction is effectively exploited to generate trans-hydroindanes with high selectivity.

The Diels-Alder cycloaddition copolymerization of a bis(diene) with ionizable bis(dienophiles) via a cation radical mechanism has been accomplished using tris(4-bromophenyl)aminium hexachloroantimonate as a catalyst in dichloromethane solvent. The reactions occur at 0Β°C and yield Diels-Alder polymer
