Procedure

A ceph-2-em or ceph-3-em reaction product may also be oxidised to yield the corresponding ceph-3-em 1-oxide, for example by reaction with a peracid, e.g. peracetic or m-chloroperbenzoic acid; the resulting sulphoxide may if desired, subsequently be reduced as described hereinafter to yield the corresponding desired ceph-3-em sulphide.
