Abstract

An efficient metal-catalyzed hydroalkylation of various styrenes, norbornene, and cyclohexadiene with 1,3-dicarbonyl compounds has been developed. This new bismuth-catalyzed C-H functionalization provides the corresponding alkylated pentanediones in good to excellent isolated yields after short reaction times.

Key words

hydroalkylation - hydroarylation - benzylation - bismuth - C-H activation - catalysis - styrene - alkene
