Aryl ketones substituted in ortho, meta, and para position are prepared by a palladium-catalyzed Sonogashira reaction followed by a regioselective hydration of the so-formed alkyne with triflimidic acid or a gold catalyst, under catalytic conditions. This methodology opens a way to obtain substituted aryl alkyl ketones from readily available starting materials, haloarenes, and terminal alkynes. The

a typical antipsychotic drug (APD) associated with an increased risk of extrapyramidal side effects (EPSs) and hyperprolactinemia relative to atypical APDs such as clozapine. Both drugs are dopamine D2 receptor (D2R) antagonists, with contrasting kinetic profiles. Haloperidol displays fast association/slow dissociation at the D2R, whereas clozapine exhibits relatively slow association/fast dissociation
