A nucleophilic substitution of allylic alcohols with carbon (arene, heteroarene, allyltrimethylsilane, and 1,3-dicarbonyl compound), sulfur (thiol), oxygen (alcohol), and nitrogen (sulfonamide) nucleophiles has been demonstrated using an in house developed [Ir(COD)(SnCl3)l(μ-Cl)]2 heterobimetallic catalyst in 1,2-dichloroethane to afford the corresponding allylic products in moderate to excellent yields

Reported herein is a mild synthesis of 3-allylindoles via Rh(III)-catalyzed allylic C–H activation of olefins and coupling with o-alkynylanilines. The reaction proceeded via initial nucleophilic cyclization of o-alkynylanilines followed by oxidative coupling with allylic C–H bonds via an η3-allyl intermediate.

been found to be an efficient catalyst for the disproportionation of allylicalcohols, which provides a convenient method for selective transformation of allylicalcohols to alkenes and α,β-unsaturated ketones. Furthermore, this catalytic system is also effective for highly selective allylicreduction of allylicalcohols, allylic ethers, and allylic acetates with benzyl alcohol under neutral and convenient

Iron-catalyzed direct reduction of allylic halides with benzylic alcohol was achieved, providing a new, simple, and efficient method for conducting highly regioselective hydrodehalogenation. This method not only features a readily available reductant, an inexpensive catalyst, simple manipulation, and good tolerance of functional groups including nitriles, nitro, esters, and methoxyl groups, it also
An efficient allylic C−H phosphorylation has been achieved through the DDQ‐promoted cross‐dehydrogenative coupling of 1,3‐diarylpropenes with P(O)H compounds at room temperature. This method provides a convenient route to allylphosphonates in up to 97% yield with good functional group compatibility.
