Unsymmetric telechelic siloxanes with SiH and stabilizer end groups

An Efficient Catalytic Route for the Synthesis of Silane Coupling Agents Based on the 1,1,3,3‐Tetramethyldisiloxane Core

“…Unsymmetrically substituted siloxanes, that is, those having on one side the Si–H moiety and on the opposite side a reactive or specific functional group, can be prepared by two routes, namely, by the hydrolysis and co‐condensation of appropriate monochlorosilanes (RMe 2 SiCl and HSiMe 2 SiCl) or by the condensation of silanolates (RMe 2 SiOLi) with HSiMe 2 Cl as well as by the partial functionalization of 1,1,3,3‐tetramethyldisiloxane (TMDSO) with various organic or organosilicon unsaturated reagents by the hydrosilylation reaction. On the basis of the literature data, the latter is the most convenient and common protocol used for obtaining derivatives of this type.…”
