Oxidative Deprotection of Trimethylsilyl Ethers with Tetrabutylammonium Periodate (TBAPI) in the Presence of AlCl3 and BF3 in Aprotic Solvents
Structurally different trimethyl silyl ethers are oxidized with Bu4/NIO4 in the presence of AlCl3 and BF3 as catalysts in CH3CN and CHCl3 under reflux conditions. The corresponding carbonyl compounds are isolated in good yields.
متن کاملRice husk ash (RHA): A Highly efficient solid acid catalyst for the oxidation of alcohols and trimethylsilyl, tetrahydropyranyl and methoxymethyl ethers with CrO3
A mild, efficient and fast method for the oxidation of alcohols and trimethylsilyl, tetrahydropyranyl and methoxymethyl ethers to their corresponding carbonyl compounds using CrO3 in the presence of rice husk ash (RHA) is reported. All reactions were performed at room temperature in high to excellent yields. A new, efficient and green catalyst, heterogeneous reaction conditions, easy work-up of...

متن کاملAmmonium Decatungstocerate(IV): An Efficient Catalyst for the Protection and Deprotection of Tetrahydropyranyl Ethers
In multi-step organic syntheses, the protection and deprotection of tetrahydropyranyl (THP) ethers is one of the most frequently used methods. Over the years, different methods have been used from various catalytic systems for the protection of hydroxyl groups as THP ethers and their deprotection. Herein we have reported that various alcohols and phenols have been efficiently converted to the c...
