Abstract

A simple and efficient method for the conversion of alcohols and phenols into their corresponding THP and THF ethers at room temperature has been developed using 1mol% aluminium triflate as catalyst. The deprotection reaction in the presence of methanol using Al (OTf) 3 was equally successful and could be performed at ambient temperature in high yields.
