Abstract
The reported BiBr3–Et3SiH catalyzed reductive etherifications of silyl ethers with carbonyl compounds are shown to be catalyzed by the in situ formed Et3SiBr and verified by an independent use of the commercial reagent. As Et3SiBr is moisture sensitive and is not readily available, this in situ generation is still recommended as the method of choice. Utilizing this method, several alcohols were transformed under very mild conditions into dialkyl ethers via their silyl intermediates, such as TES, TBDMS, and TIPS.
