Stereoretentive Pd-catalyzed kumada-corriu couplings of alkenyl halides at room temperature

Stereoselective palladium-catalyzed Kumada-Corriu reactions of functionalized alkenyl halides and a variety of Grignard reagents, including those bearing β-hydrogen atoms and sensitive functional groups, can be carried out at room temperature using a new combination of reagents.

Ligand effects on Negishi couplings of alkenyl halides

Negishi couplings at olefinic centers do not always occur with the anticipated maintenance of stereochemistry. The source of erosion has been traced to the ligand, and a modified method has been developed that solves the stereochemical issue and significantly improves yields of Negishi couplings in general.

Use of InCl3 as a cocatalyst and a Cl2Pd(DPEphos)- P(2-Furyl)3 catalyst system for one-pot hydrometalation-cross- coupling and carbometalation-cross-coupling tandem processes

One-pot conversion of alkynes to regio- and stereodefined alkenylmetals containing Al and Zr via hydrometalation or carbometalation followed by their Pd-catalyzed cross-coupling with (E)-ICH=CHBr or (E)-ICH=CHCl proceeds cleanly and selectively to give the corresponding 1-halo1,3-dienes in excellent yields using a catalyst system consisting of Cl2Pd(DPEphos), DIBAL-H, and TFP (catalyst A) with InCl3 as a cocatalyst.
