N-(4-Chlorophenyl)-9H-fluoren-9-imine

Abstract

The title compound, C19H12ClN, was synthesized via reaction of 9-fluorenone and 4-chloroaniline using p-toluenesulfonic acid in toluene. The dihedral angle between the fluorene moiety (r.m.s. deviation = 0.027 Å) and the chlorophenyl ring is 64.59 (6)° and a possible weak intramolecular C—H...π interaction occurs.
