Penicillin and cephalosporin imino halides are prepared by reacting of 6-acylaminopenicillins or 7-acylamino cephalosporins with a novel chlorinating compound derived from a triaryl phosphite and chlorine or bromine. The imino halide products are intermediates in the preparation of antibiotic compounds.
