Co-Catalyzed Direct Addition of Allylic C(sp3)-H Bonds to Ketones

By using Co(acac)2/Xantphos with AlMe3, the C(sp3)-H bonds of allylarene derivatives were cleaved for reaction with various ketones, affording the homoallylic alcohols in moderate to good yields. The branch/linear selectivity depended on the steric and electronic factors of the ketone electrophiles. The intermediate in this reaction is thought to be a low-valent allylcobalt(I) species, which exhibits high nucleophilicity toward ketones.

Visible-light-mediated alkylation of 4-alkyl-1,4-dihydropyridines with alkenyl sulfones

Herein we report a mild, general protocol for visible-light-mediated alkylation of 4-alkyl-1,4-dihydropyridines with alkenyl sulfones. The protocol permits efficient functionalization of sulfones with a broad range of cyclic and acyclic secondary and tert

Visible-Light-Mediated Alkenylation of Alkyl Boronic Acids without an External Lewis Base as an Activator

Herein we report a protocol for the direct visible-light-mediated alkenylation of alkyl boronic acids at room temperature without an external Lewis base as an activator, and we propose a mechanism involving benzenesulfinate activation of the alkyl boronic acids. The protocol permits the efficient functionalization of a broad range of cyclic and acyclic primary and secondary alkyl boronic acids with various alkenyl sulfones. We demonstrated its utility by preparing or functionalizing several pharmaceuticals and natural products.

Alkenyl-copper derivatives 19. Synthesis of conjugated dienes and styrenes by cuopling of alkenyl cuprates with alkenyl and aryl halides

Z dialkenylcuprates obtained by carbometallation of acetylene couple easily with alkenylhalides and iodoarenes in the presence of ZnBr2 and a catalytic amount of NiL4 or Pd0L4 to afford high yields of conjugated dienes and styrenes with very high stereoselectivity.Such pure dienes are often encountered in insect sex pheromones.
