Abstract:
A method of preparing a trialkylsilane for use in chromatographic applications, the method comprising:(a) preparing a disubstituted vinylsilane by reacting an organomagnesium reagent and a vinylfunctional silane; (b) reacting the disubstituted vinylsilane of step (a) and a monomeric silane containing a silicon-hydrogen bond in the presence of a metallic catalyst, such that the monomeric silane is added to a vinyl group of the vinylsilane, thereby binding the silicon of the monomeric silane to a terminal carbon of the vinyl group and forming a trialkylsilane having a terminal trialkylsilyl moiety, wherein at least two alkyl groups of the trialkylsilyl moiety independently comprise at least six carbons atoms and the at least two alkyl groups extend from a silicon of the prepared disubstituted vinylsilane of step (a).
