Abstract
Methyl 2-Br-2-Cl-carboxylates afford 2-alkyl-2-Cl-4-Br-carboxylates in fair yields by reaction with terminal alkenes, under mild conditions, through a radical process promoted by CuBr/Fe0 in DMF/CH2C12.
Notes
Other solvent like THF, DMSO/CH2Cl2, CH3CN/CH2Cl2 were also tested but with unsatisfactory outcomes.
