Notes:
Chlorinated diphenylsiloxanes were prepared by acid- and base-catalyzed polymerization of the corresponding diols in polar organic solvents. Under mild conditions, cyclic tetramers were isolated. More forcing conditions in the presence of base yielded resins containing largely cyclic species which showed extensive cleavage of the phenyl groups. The order of the phenyl group cleavage among the polymers indicated that the inductive effect of the substituent halogen plays a dominant role.
