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

Various functionalized cyclicethers such as oxiranes, oxetanes, and tetrahydrofurans have been prepared, and the regiochemistry of their ring opening with samarium diiodide and acyl chloride or anhydride has been investigated. Alkyl-substituted oxetane 5 and tetrahydrofurans 1 and 2 show almost no regioselectivity. However, high regioselectivities from the branched cyclicethers (3, 8, 9, and 10) containing

Regioselective cleavage of 2-methyltetrahydrofuran with bulky acid iodides RCOI gives predominantly the primary iodides, while acid chlorides RCOCl lead to secondary chlorides almost exclusively, regardless of the nature of R.
