Zusammenfassung:Cephalosporin derivatives of formula (I): wherein R is an acyl group of the formula: wherein R min is a 5- or 6-membered heterocyclic ring and +/ &cir& R1 is an optionally substituted thieno- or furo-pyridinium system are particularly effective antibacterial agents; or (R is hydrogen) useful intermediates. Also disclosed is the useful and novel intermediate 2-carboxy-thieno(3,2-c)pyridine sec .
