Definition

ChEBI: 4-Fluorobenzonitrile is a member of benzenes and a nitrile.

General Description

4-Fluorobenzonitrile undergoes metal-mediated coupling to yield eight-membered thorium(IV) tetraazamacrocycle. It undergoes condensation with diphenylamine to yield monomer 4-cyanotriphenylamine.

Synthesis

4-Fluorobenzonitrile is synthesised using 4-Fluorobenzyl alcohol as raw material by chemical reaction. The specific synthesis steps are as follows:
With respect to 2 mmol of each alcohol represented by the general formula (1), 4 ml of CH2Cl2 as a solvent, 0.05 equivalent of TEMPO as an N-nitrosyl compound, (A) t-BuOCl, (B) I 2 or (C ) N, N'-diiodo-5,5-dimethylhydantoin (DIH) were mixed in a predetermined amount and stirred for a predetermined time at room temperature.Next, 1.5 equivalents of I 2 and 4 ml of aqueous ammonia were added, and the mixture was stirred at room temperature for 2 hours.
