Abstract

Abstract : A halogen-free synthesis of methoxysilyl-substituted double-four-ring (D4R) siloxanes [Si8 O12 ][OSiR(OMe)2 ] (R = OMe or vinyl) was accomplished. Abstract : The synthesis of methoxysilyl-substituted siloxanes with a double-four-ring (D4R) framework [Si8 O12 ][OSiR(OMe)2 ]8 (R = OMe or vinyl) via the dealcoholative coupling between silanol [Si8 O12 ][OH]8 and alkoxysilane was accomplished and achieved a halogen-free synthetic process. The solid-state structure of [Si8 O12 ][OSi(OMe)3 ]8 was determined via a single-crystal X-ray diffraction analysis.
