Transition metal-catalyzed direct C–H bond functionalization enabled by transient ligands has become an attractive topic. Here we report a palladium-catalyzed site-selective arylation of β-C(sp3)–H bonds in aliphatic ketones with β-alanine as the transient ligand.

Triarylstibines react with α,β-unsaturated aldehydes and ketones in acetic acid at 25°C in the presence of silveracetate and a catalytic amount of palladium(II) acetate to afford the hydroarylation products by conjugate addition in good yields.

Triarylstibines react with α,β-unsaturated ketones and aldehydes in acetic acid at room temperature in the presence of AgOAc and a catalytic amount of Pd(OAc)2 to afford the conjugate addition products (the formal hydroarylated compounds to an olefinic part) in good yields. In contrast, diarylantimony chlorides, arylantimony dichlorides, and diphenylantimony acetate react with the enones and enals

enantioselectivity, using acetic acid or water as the hydrogen source and indium powder as electron donor. The scope of alkenes herein include α,β-unsaturated esters, nitriles, and ketones as well as allylicalcohols. Asymmetric deuteration of α,β-unsaturated esters is also achieved with deuterated water, the cheapest deuterium source.
