主　　题：α-Monobromination β-Ketoesters Pyridinium bromochromate 1,3-Diketones 

摘      要：Pyridinium bromochromate has been found to be a highly efficient and selective reagent for the α-monobromination of 1,3- diketones and β-keto-esters in the absence of base, Lewis acid, or other catalyst. The products were formed in high to excellent yields under mild reaction conditions and in short reaction times.
