The detailed procedure and mechanistic analysis for the synthesis of polymethylhydrosiloxane‐based semi‐interpenetrating networks (PMHS‐SIPNs) with Si−H and other functional groups under mild reaction conditions was presented in this work. And the Si−H –containing organosilicon materials was proved to be a useful support in the construction of nanosilver catalyst according to the previous reported strategy that with the concept of titanium‐promoted reduction of ester with hydrosilane for well‐distributed dispersion of titanium and nanosilver on cross‐linked PMHS‐SIPNs supporter (Ag@TiO 2 @PMHSIPN). Furthermore, a highly efficient method for the synthesis of primary propargylic alcohols has been developed using PMHS‐based semi‐interpenetrating networks –supported nanosilver (Ag@TiO 2 @PMHSIPN) as catalyst.
