Abstract A simple and efficient protection of alcohols as trityl ethers is described using trityl chloride in the presence of 5 mol% FeCl3 as catalyst in ionic liquids at room temperature in shorter reaction times. This mild and efficient method gives access to the protection of a wide range of alcohols in good yields. The use of ionic liquid allows easy separation of the product and recycling of catalyst
