of R chains of amides R1C(O)NHR, a fundamental class of synthetic substrates, has not been accomplished to date. Here, the first example of palladium(II)-catalyzed alkynylation of an unactivated gamma C(sp3)–H bond of alkyl amides (cyclic, linear, and amino acids) is reported. The kinetic experiment shows that the rate of the reaction depends on the coupling partners and the amides. Late-stage diversification
