Thionyl Chloride → 3,5-Dichloro-5H-dibenzo[a,d]cycloheptene

Participants

Reaction Steps

The thus dried 3-chloro-5H-dibenzo[a,d]cyclohepten-5-ol intermediate was mixed with 10 milliliters of benzene and 10 milliliters of thionyl chloride and the resulting mixture stirred at reflux temperature for 2 hours to obtain 3,5-dichloro-5H-dibenzo[a,d]cycloheptene intermediate in the reaction mixture. The mixture was cooled and evaporated under reduced pressure to recover the chloro intermediate as residue.
