Palladium‐catalyzed β‐C(sp3)‐Harylation of aliphatic acid derivatives was achieved by means of 2‐dimethylaminoethylamine auxiliary as a directing group. The β‐C(sp3)‐Harylation reactions with aryl and heteroaryl iodides efficiently afforded the corresponding arylated hydrocinnamic acid derivatives. Direct β‐C(sp3)‐H alkynylation, and arene C−H arylation and alkynylation were also realized under the

Carboxylicacids are highly abundant in bioactive molecules. In this study, we describe the late-stage β-C(sp3)–H deuteration of freecarboxylicacids. On the basis of the finding that C–H activation with our catalysts is reversible, the de-deuteration process was first optimized. The resulting method uses ethylenediamine-based ligands and can be used to achieve the desired deuteration when using a
