Organotin Polyesters from 1,1′-Ferrocenedicarboxylic Acid

Organotin polyesters have been synthesized employing the classical interfacial polycondensation of organotin dihalides and the salt of 1,1′-ferrocenedicarboxylic acid. The products are oligomeric (DP = 5) to polymeric (DP = 220). The presence of new IR bands characteristic of formation of the Sn–O band are present. Ion fragments characteristic of the repeat unit and greater are found employing F MALDI...
