Acetyl tosylate

Dialkyl ethers can be cleaved by treatment with anhydrous ferric chloride in acetic anhydride.700 In this reaction both R groups are converted to acetates. Yields are moderate to high. Ethers can also be cleaved by the mixed anhydride acetyl tosylate 701... [Pg.400]

Methyltetrahydrofuran allowed to react 12hrs. at 25° with acetyl tosylate -> 1-acetoxypentyl 4-p-tosylate. Y 95%. - Catalysis by added Lewis acids is not necessary and cleavage of the most unreactive ethers occurs after a few hrs. reflux in acetonitrile. The cleavage of unsym. ethers favors a greater specificity than other methods. M. H. Karger and Y. Mazur, Am. Soc. 90, 3878 (1968). [Pg.43]
