Microwave-induced selective synthesis of α-bromo and α,α-dibromoalkanones using dioxane–dibromide and silica gel under solvent-free conditions

Selective synthesis of α-bromo and α,α-dibromoalkanones using dioxane–dibromide and silica gel in solvent-free conditions under microwave irradiation has been reported. The amount of dioxane–dibromide, silica gel and time of irradiation are keys for the selective synthesis of α-bromo and α,α-dibromoalkanones.
