Abstract

A procedure for obtaining a deacetoxycephalosporin derivative of the formula **(See formula)** (where R1 is an acyl group and -COOR2 is a free or esterified carboxyl group), which comprises heating a penicillin sulfoxide of the formula **(See formula)** (where all symbols have the same meanings defined above) with an azo compound of the formula **(See formula)** (where -COR3 is an esterified or amidated carboxyl group and R4 is an esterified or amidated carboxyl group, a hydrocarbon moiety, or -COR3 and R4 form a monocyclic nucleus together with the adjacent group (-N = N)).
