Abstract

A process for the preparation of 3-alkylthiomethyl-7-acylamidocephalosporins which consists in reacting a 3-alkanoyloxy-ethyl-7-acylamidocephalosporin with an alkanethiol, the reaction being carried out in an aqueous medium in the presence of inorganic salts selected from the highly water-soluble salts of iodide, bromide, thiocyanate, nitrate or sulfate of the metals of groups i and ii or ammonium iodide.
