Catalytic Radical Addition of Carbonyl Compounds to Alkenes by Mn(II)/Co(II)/O2 System

Abstract
The radical addition of enolizable carbonyl compounds such as malonates and malononitrile to alkenes was successfully achieved through a catalytic process using the Mn(II)/Co(II)/O2 system to afford the corresponding adducts in fair to good yields. Dimethyl malonate added to 1,5-cyclooctadiene to produce a fused bicycle compound.
