Abstract
Abstract Reductive removal of the bromine atom(s) of 6,6-dibromo- and 6-bromopenicillanate 1-oxides has been performed successfully on treatment with aluminum metal in the presence of a catalytic amount of lead(II) bromide in methanol containing 1% aqueous hydrobromic acid. In a similar manner, 6,6-dibromopenicillanates and their 1,1-dioxides can be convened to the corresponding debromination products, respectively.
