摘要:
New cephalosporin derivatives of the formula: ##STR1## in which R' represents a protected carboxyl radical, Hal represents a halogen atom, X.sub.1 represents a sulphur or oxygen atom or a sulphinyl radical and R represents an acyl radical or an amine-protecting radical, are useful as intermediates for the preparation of cephalosporins having antibacterial activity.
