An ammonium iodide catalyzed direct oxidative coupling of silanes with alcohols to give various alkoxysilane derivatives was discovered. tert-Butyl hydroperoxide proved to be an efficient oxidant for this transformation. Attractive features of this protocol include its transition-metal-free nature and the mild reaction conditions.

electrochemical approaches for NaCl-mediated hydrolysis of hydrosilanes have been well established to prepare silanols in moderate to good yields with good functional group tolerance under ambient conditions. Furthermore, electrochemical NaBr-promoted alcoholysis of hydrosilanes with a series of alcohols was successfully achieved under metal-free conditions. The synthetic application of eco-friendly

An efficient chemoselective iridium-catalyzed method for the hydroxylation and alkoxylation of organosilanes to generate hydrogen gas and silanols or silyl ethers was developed. A variety of sterically hindered silanes with alkyl, aryl, and ether groups were tolerated. Furthermore, this atom-economical catalytic protocol can be used for the synthesis of silanediols and silanetriols. A one-pot silane
