AbstractOligomeric Group IVA ferrocene Polyesters were synthesized utilizing the interfacial condensation technique. Yield decreases with increasing complexity of the aliphatic substituent; it decreases in the order of I>Br>Cl, and it decreases in the order of Sn>Ge>Si. Thus, initial attack by the nucleophile, steric requirements, and metal—halide bond breakage appear important:Where M = Si, Ge, or S
