Gaseous nitrogen dioxide for sustainable oxidative deprotection of trimethylsilyl ethers

In this study, trialkylsilyl ethers of indispensable protected alcohols are oxidatively deprotected in neat form with gaseous nitrogen dioxide (NO 2). Quantitative yields of aldehydes or ketones are obtained without the necessity of chromatography. The byproducts, nitrogen monoxide, anhydrous nitric acid, and hexamethyldisiloxane, can be quantitatively separated by evaporation and distillation in closed systems for recycling or further use. The direct new method supersedes the previous techniques that produce dangerous wastes and require chromatographic workup, while the atmospheric gas NO 2 and its gaseous reduction products are easily kept in closed systems until further use.

Regeneration of the carbonyl compounds from their semicarbazones using tetra-n-alkylammonium bromates

Tetra alkyl ammonium bromates are prepared by a simple procedure and used for the oxidative regeneration of the parent carbonyl compound from their semicarbazones. Reaction conditions are simple and the deprotection gives satisfactory yield of the carbonyl compound.
