alcohols and carboxylic acids. The reaction of various alcohols and carboxylic acids with TriAT-tBu in the presence of a catalytic amount of an acid provided the corresponding tert-butyl ethers and esters in good to high yields. TriAT-tBu is an air-stable solid synthesized in good yield from inexpensive starting materials, namely, cyanuric chloride, tBuOH, and sodium hydride.
