Rhodium(III)-Catalyzed Directed C-H Dienylation of Anilides with Allenes Leads to Highly Conjugated Systems

Allenes are unique coupling partners in transition-metal-catalyzed C-H functionalization leading to a variety of products via alkenylation, allenylation, allylation, and annulation reactions. The outcome is governed by both the reactivity of the allene and the formation and stability of the organometallic intermediate. An efficient Rh(III)-catalyzed, weakly coordinating group-directed dienylation of electronically unbiased allenes is developed using an N-acyl amino acid as a ligand. Further elaboration of the dienylated products to construct polycyclic compounds is also described.

Multicomponent Coupling Reactions of Two N-Tosyl Hydrazones and Elemental Sulfur: Selective Denitrogenation Pathway toward Unsymmetric 2,5-Disubstituted 1,3,4-Thiadiazoles

A copper-mediated, three-component reaction between two different N-Ts hydrazones and elemental sulfur was developed, leading to a series of unsymmetric 2,5-disubstituted 1,3,4-thiadiazoles in moderate yields with good functional group compatibility. This

Palladium-catalyzed formal hydroacylation of allenes employing acid chlorides and hydrosilanes

The palladium-catalyzed formal hydroacylation of allenes employing acid chlorides and hydrosilanes has been achieved. The reactions proceed with commercially available Pd(OAc)2 as a catalyst and HSi(iPr) 3 as a reducing reagent, giving the corresponding α,β-unsaturated ketones regio- and stereoselectively.
