Due to the strong potential of C-H activation in many areas of organic chemistry, the use of a pre-existing carbonyl group for the installation of a directing group to enable selective and predictable α-alkenylation with activated olefins as coupling partners is described. This Heck-type reaction would then lead either to β,γ-unsaturated ketones or to variously substituted 1,4-butadienes depending on the conditions used for the cleavage of the directing group.

RhIII-catalyzed C-H activation with allenes produces highly unsaturated conjugated olefins. The reaction is applicable to both olefin and arene C(sp2)-H and is compatible with a variety of functional groups. The products can be further transformed into ot

(Figure Presented) Suzuki-Miyaura coupling of unactivated alkenyl carbamates Is described to construct polysubstituted olefins. The developed process is also suitable for heteroaromatic and even electron-rich aromatic carbamates.

The rhodium-catalyzed asymmetric hydrogenation of different acyclic and cyclic enol carbamates to give optically active carbamates has been examined in the presence of chiral monodentate ligands based on a 4,5-dihydro-3H-dinaphthophosphepine motif 4. The

(Chemical Equation Presented) Monodentate phosphoramidites, in particular PipPhos and its octahydro analogue, are excellent ligands for the rhodium-catalyzed asymmetric hydrogenation of aromatic enol acetates, enol carbamates, and 2-dienol carbamates up to 98% ee. These latter substrates were hydrogenated selectively to the carbamates of the allyl alcohol.
