Reaction of Adamantan-1-ol with Lower Alcohols in the Presence of CuBr2.

The reaction of adamantan-1-ol with lower alcohols (methanol, ethanol) in the presence of water and an equimolar amount of CuBr2 (with respect to adamantan-1-ol) at 220°C for 4 h gives adamantane in a high yield. (E)-(Prop-1-en-1-yl)adamantane was obtained in a high yield from adamantan-1-ol and isopropanol under similar conditions but in the absence of water. [ABSTRACT FROM AUTHOR]
