AbstractThe transition metal‐catalyzed transfer of silicon nucleophiles onto various electrophiles has recently gained considerable attention, due to the now readily available silicon pro‐nucleophiles such as silylboronates. Our interest lies in the addition of such species to acid derivatives for the generation of acylsilanes. We report herein an efficient method to synthesize these compounds, starting from easy‐to‐form anhydrides, with very good yields.magnified image
Zinc-catalyzed synthesis of acylsilanes using carboxylicacids and a silylborane has been achieved in the presence of pivalic anhydride. Various carboxylicacids were converted to the corresponding acylsilanes. The in situ formation of mixed anhydrides was essential in the present reaction.
