Abstract

Etherification by direct coupling of alcohols is a useful method in organic synthesis. 1 The reaction is generally carried out by using a small amount of an inorganic or organic acid. The Williamson ether synthesis, 2 one of the most commonly used methods, requires the conversion of alcohols to halides or tosylates. Various Lewis acids such as FeCl3, 3 BiBr3, 4 ZnCl2, 6 GaCl3, 6 methylrhenium trioxide7 and rare earth metal triflates8 can also ...
