Zusammenfassung:Novel cephalosporins of the general formula are obtained by reaction of a 3-acetoxymethylcephalosporin of the formula with a triazinylthio derivative of the formula The substituents are defined in Claim 1. If necessary, the amino and/or carboxyl groups are intermediately protected and, if it is desired, the compounds obtained according to the invention are acylated by the known processes. The reaction is preferably carried out in polar solvents, e.g. water. These novel cephalosporins are to be used on the one hand as medicines having antibiotic activity or on the other hand as intermediates in the preparation of antibiotics.
