Preparation and Properties of 7α-Formamido Cephalosporins

The preparation of novel antibacterially active 7α-formamido cephalosporins from the corresponding 7α-(methylthio) analogues by mercury(II)-mediated displacement with ammonia and subsequent formylation is described.The amine (2), a versatile intermediate,
