Ethane-1,2-diyl)dipyridinium bistribromide (EDPBT) as an organocatalyst for the silylation/desilylation reaction

1,1’-(Ethane-1,2-diyl)dipyridinium bistribromide (EDPBT) was used as a chemoselective and effective organocatalyst for the silylation of hydroxyl groups as well as desilylation of trimethylsilyl ethers under mild conditions at room temperature with good to excellent yields.
