The reaction of 2-aminoaryl ketones and arynes generated by the treatment of various o-(trimethylsilyl)aryl triflates with CsF results in [4 + 2] annulation to afford Substituted acridines in good yields.

An efficient synthesis of 9‐aryl‐substitutedacridines from cyclohexanones and 2‐aminobenzophenones under palladium‐catalyzed conditions was developed. By using molecular oxygen as a green oxidant, various cyclohexanones act as the aryl source to construct the nitrogen‐containing heterocycles through a condensation/cyclization/tautomerization sequence.
