A novel catalytic decarbonylative Heck-type reaction and conjugate addition of aldehydes to unsaturated carbonyl compounds
A novel rhodium-catalyzed decarbonylative reaction of aldehydes with unsaturated carbonyl compounds was discovered to generate Heck-type reaction product and conjugate addition product.
Selective arylation of 1,1-disubstituted olefins using a biphenyl-based phosphine in Heck coupling reactions
The biphenyl-based phosphine, 2-diphenylphosphino-2′-methylbiphenyl is an effective ligand for palladium-catalyzed terminal arylation of 1,1-disubstituted olefins with aryl bromides in DMF and K2CO3 as base. The yields of products are independent of the electronic properties of the aryl bromides, however, the nature of the olefin has a major effect.
