Herein we report a nickel/photo-cocatalyzed C(sp2)-H allylation of aldehydes and formamides wherein both allyl acetates and allyl alcohols can be used as the allylating agents. In this reaction, radical-type umpolung of the formyl moiety is enabled by tetrabutylammonium decatungstate as a hydrogen-atom-transfer photocatalyst, whereas nickel serves to cleave the C-O bond of allyl acetates or allyl alcohols. The synergistic effect of these two catalysts provides new access to various β,γ-unsaturated ketones and amides with high selectivities.

α-Arylcarboxylic acid amides were synthesized by reacting silyl enol ethers of aryl ketones and 2-azido-1,3-dimethylimidazolinium hexafluorophosphate (ADMP,1). Silyl enol ethers react with ADMP 1 to give N-(α-arylacyl) guanidines via the migration of aryl groups in enol ethers. The products were transformed to the corresponding α-aryl acetamides by treating with LiAlH4.

(Chemical equation presented) Alkenylation reaction of α-halo carbonyl compounds with alkenylindiums proceeded via a radical process in the presence of triethylborane. Unactivated alkene moieties as well as a styryl group could be introduced by this metho
Synthesis of allylamides from allyl halides, carbon monoxide, and titanium-nitrogen complexes prepared from molecular nitrogen

4-Phenylbut-3-enamide could be synthesized from corresponding 3-chloroprop-2-enylbenzene, carbon monoxide (1atm), and titanium-nitrogen complexes, prepared from Ti(OiPr)4, Li, TMSCl, and molecular nitrogen (1atm), using a palladium catalyst. The reaction proceeds via transmetalation of the titanium-nitrogen complex to an acylpalladium complex. PtBu3 as a ligand of the palladium catalyst, afforded a good result, and the amounts of Li and TMSCl affected the yield of amide. When the reaction was carried out using a bidentate ligand on the palladium complex under an atmosphere of argon instead of carbon monoxide, an allylamine derivative was obtained.

The palladium-catalyzed vinylation of benzylic tributylammonium salts with a variety of olefins has been studied. A possible free radical mechanism is proposed.
Aza- and oxacarbonylations of allyl phosphates catalyzed by rhodium carbonyl cluster. Selective synthesis of β,γ-unsaturated amides, esters, and acids

Rhodium-catalyzed carbonylation of allyl phosphates under CO (20 atm) at 50 deg C proceeds very efficiently in the presence of amines, alcohols, and water to give the corresponding β,γ-unsaturated amides, esters, and acids, respectively.These carbonylations occur with high regioselectivity at the less substituted carbon of allyl unit to give linear β,υ-unsaturated acid derivatives.
