ABSTRACT:
A synthetic process for the selective preparation of reactive polyhedral oligomeric silsesquioxanes (POSS) as well as polyhedral oligomeric silicate (POS) (spherosilicate) is provided. The inventive process employs the use of metal catalyzed hydrosilylation reactions for the selective reaction of silane containing polyhedral oligomeric silsesquioxanes or silicates with olefinic reagents bearing functionalities useful for grafting reactions, polymerization chemistry and sol-gel processes. The invention also discloses metal-catalyzed hydrosulfidation reactions and metal-catalyzed hydrophosphidation reacttions for functionalization of polycyclic silicones.
