In the last decade, microwave promoted reactions under solvent-free conditions have received considerable attention as a powerful technique to effect various organic transformations. 14 Very recently, microwave induced α-bromination of ketones achieved under solvent-free conditions by use of dioxane–dibromide in combination with silica gel. 15 In addition, we recently reported the use of N-iodosuccinimide and p-toluenesulfonic acid for facile microwave induced α- ...
