Abstract
Fluoride catalyzed rearrangement reactions of polymeric silsesquioxanes [RSiO]involve reacting at least one silsesquioxane material with a catalytic amount of an organic fluoride at a temperature ranging from about −50° C. to about 120° C. thereby forming a reaction mixture for a period ranging from 60 minutes to 48 hours. To the reaction mixture, a quenching agent is added to remove fluoride from the reaction mixture. A silsesquioxane cage compound can be isolated from the reaction mixture using a precipitation or other extraction process.
