Acylation of (Hetero)Arenes through CH Activation with Aroyl Surrogates

In this Minireview, the major achievements in the acylation of arenes and heteroarenes by CH activation with aroyl groups are summarized and discussed. As the products are carbonyl‐containing compounds that are typical products from carbonylation chemistry, the possible inspirations for these reactions are also discussed, as are mechanistic issues and possible problems for carbonylative diaryl ketone synthesis by CH activation. In splendid acylation: The major achievements in the acylation of arenes and heteroarenes by CH activation with aroyl groups are summarized and discussed, based on the aroyl sources employed. In light of these achievements and their mechanistic studies, possible problems for carbonylative diaryl ketone synthesis by CH activation are also discussed (see scheme; DG=directing group).
