Abstract

Sulfamic acid has been used as an efficient catalyst and green alternative for metal- containing acidic materials to promote the acetolysis reaction of THF to produce 1, 4- diacetoxybutane. This method is also applicable to the acetolysis of other cyclic ethers, such as methyl substituted THF and tetrahydropyran and 1, 4-dioxane, which is less reactive.
