Aromatic Ketones Containing One Pivaloyl Group

Martin, Aromatic Hydroxyketones Preparation and Physical Properties, [Pg.2083]

Also obtained by Friedel-Crafls acyladon of phenol (1 mol) with pivaloyl chloride (1 mol) in the presence of stannic chloride (2 mol) in nitromethane at 20° for 6 days (26%) [8300]. [Pg.2084]

Also obtained from p-acetoxybenzoyl chloride by treatment with lithium tert-butoxide and tert-butyUithium in a mixture pentane/tetrahydrofurane in the presence of cuprous iodide, followed by hydrolysis (80%) [6683]. [Pg.2084]

Also obtained by an ultrasound assisted iodine catalyzed Friedel-Crafts acylation of phenol with pivaloyl chloride for 10 min at r.t. (84%) [8301]. The same pivaloylation, carried out at silent (non-ultrasound) conditions, gave only, after 6 h at r.t., a yield of 62%. [Pg.2084]
