Abstract
AbstractAn imidazolyl Schiff base‐containing periodic mesoporous organosilica (PMO) was synthesized via co‐condensation reactions between a newly prepared bis (imidazolyl)imine‐bridged bis silane and tetraethyl orthosilicate in the presence of cetyltrimethyl ammonium bromide as a soft template. The resultant as‐synthesized PMO was then employed as a solid support for platinum catalysts. This complex was fully characterized via various techniques including FTIR, solid‐state13C NMR, and 29Si‐NMR spectroscopy, as well as N2 adsorption/desorption analysis, X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) methods. In addition, the catalyst was proven to efficiently mediate hydrosilylation reactions between olefins and hydrosilanes, and it can be reused for at least five cycles without significant loss of activity.
