A highly stereoselective umpolung 1,4-addition of vinyl bromides to enals is enabled by NHC/palladium cooperative catalysis, generating various valuable γ,δ-unsaturated carbonyl derivatives in excellent yields (up to 90%). A detailed mechanism investigation indicates the NHC act as both organocatalyst and ligand for palladium during this system.

The coupling reactions of allylic and benzylic alcohols and allyltrimethylsilane are efficiently catalyzed by a rhenium complex to give the corresponding 1,5-dienes and alkenes in moderate to good yields. Similarly, alcohols were coupled with ketene silyl acetals to form the corresponding esters.
Rhodium-catalyzed reaction of aryl- and alkenylboronic acids with 2,4-dienoate esters: Conjugate addition and Heck reaction products

(Chemical Equation Presented) We report herein the first examples of the addition of aryl- and alkenylboronic acids catalyzed by RhI complexes to 2,4-dienoate esters. Three different types of products have been obtained depending on the substitution pattern of the starting ester and the organoboronic acid: 1,6-conjugate addition products, 1,4-conjugate addition products, and Heck reaction products.
Synthetically useful desulfurisation reactions of heteroaryl sulfoxide conjugate adducts
Casey,Gairns,Walker
, p. 1725 - 1728 (2007/10/03)
Efficient desulfurisation reactions of the conjugate addition products derived from 1-methyl-2-imidazolyl and 2-pyridyl sulfoxides have been achieved. Hydrodesulfurisation was effected either by reduction of the sulfoxides to sulfides, followed by treatment with Raney nickel, or more reliably by reaction of either the sulfides or the sulfoxides with nickel boride. Pyrolytic elimination furnished alkenes stereoselectively on heating the sulfoxides to reflux in toluene or chloroform.
