Group VA Poly(amine esters) Containing the Antibacterial Ampicillin

Polyester amines were formed from the reaction of the salt of ampicillin with triphenyarsenic, triphenylantimony, and triphenylbismuth dihalides employing the interfacial polycondensation reaction. IR shows the formation of M–OC=O and M–N bands consistent with the proposed polymer formation. Further, IR results are consistent with the repeat units connecting in a somewhat random manner about the metal atom. MALDI MS results give ion fragments to...
