A general and highly chemoselective Pd-catalyzed protocol for the synthesis of α,β-unsaturated ketones by carbonylation of vinyl triflates and nonaflates is presented. Applying the specific monophosphine ligand cataCXium A, the synthesis of various vinyl ketones as well as carbonylated natural product derivatives proceeds in good yields.

A nickel-catalyzed reductive coupling between acid fluorides and vinyl triflates has been described. This method provides an efficient access to various enones and avoids the requirement for acyl or vinyl metallic reagents in the conventional approaches.

The combined use of a catalytic amount of InX3 (X = OTf and NTf2) and 1-butanol was found to be effective in formal alkynealdehyde metathesis. With this catalytic system, aromatic alkynes reacted with aromatic aldehydes to give chalcones in moderate to good yields. Alkynals were efficiently converted into 5- to 7-membered cyclic compounds by intramolecular alkyne-aldehyde coupling.

Cyclic ketone O-trimethylsilylcyanohydrins (2) were prepared and converted to various compounds: α-hydroxyketones (3), dehydroxylated ketones (4), α,β-unsaturated ketones (9), tricyclic ketones (10), 1-ethoxycarbonyl-4- phenyl-1,2,4a,5,6,7,8,8a-octahydro-2-naphthalenone (13), 1- phenylperhydroisocoumarin (18) and 1,2,3,4,4a,10,11,11a-octahydro-5h- benzo[a,d]cyclohepten-10-one (20).
