Cyclic and acyclic ethers are regioselectively cleaved at less substituted a-carbon-oxygen bond in the absence of Lewis acid by the reagent system of sodium iodide and acyl chlorides.

## Abstract The __tert__‐butoxy derivative is one of the most underused alcohol protecting groups. After having developed an easy and useful protocol for its introduction, we offer here a simple procedure for its removal by treatment with anhydrous CeCl~3~ and NaI in CH~3~CN. The procedure led to t

A general method for the selective cleavage of tert-butyldimethylsilyl ethers in the presence of tert-butyldiphenylsilyl ones has been established using a combination of H20 and a concentrated solution of LiCI in DMF at 90 Β°C. Since no acids, bases, reducing or oxidizing agents are used, the method
