Aryl, Alkylbis-SilylEthers: Rapid Access to Monoprotected Aryl Alkyl and Biaryl Ethers

A simple one-pot procedure has been developed for the selective etherification of aryl silyl ethers in aryl, alkyl bis-silyl ethers to generate alkyl tert-butyldimethylsilyl-protected aryl alkyl ethers and biaryl ethers in good to excellent yields.
