“…[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] 8-Membered compounds such as DH 4 , because of the possible modification of peripheral Si-H groups by a hydrosilylation reaction, have opened access to several functional materials. While cyclosiloxanes have been utilized as substrates in the synthesis of dendritic molecules, 40 films 41,42 and coatings, 30,43 sensors, 44,45 liquid crystallines, 46,47 electrolytes, 48 ceramics, 49 and membranes, 50 there are no reports of their use as precursors of silica modifiers or coupling agents. The addition reactions of DH 4 to various olefins have been the subject of numerous reports.…”
