The reaction of primary alcohols or simple ethers and α,ω-diols or cyclic ethers with a stoichiometric amount of benzyltrimethylammonium tribromide (BTMA Br<SUB>3</SUB>) in carbon tetrachloride in the presence of Na<SUB>2</SUB>HPO<SUB>4</SUB> aq or in acetic acid in the presence of CH<SUB>3</SUB>CO<SUB>2</SUB>Na aq at 60–70 °C gave dimeric esters and lactones respectively in good yields. The reaction of secondary alcohols with 1 equiv of BTMA Br<SUB>3</SUB> in the presence of a buffer at 60 °C gave ketones.
