Abstract

Ruthenium‐catalyzed reaction of styrene derivatives (II) with α,α‐dichloro‐malononitrile, ‐malonate or ‐acetonitrile (I) proceeds via a double Kharasch pathway to give symmetrical or unsymmetrical 1,5‐diaryl‐1,5‐dichlorides in good yields.

## Synthesis of 5) pyrazolophanes by Sequential Intermolecular-Intramolecular Nitrilimine Cycloadditions. -Nitrilimines generated in situ from hydrazonyl chlorides such as (I) and (IV) undergo cyclization to mono-and bispyrazolophanes which are of interest in supramolecular chemistry.
