Neopentyl alcohol is acompound with formula (CH3)3CCH2OH. It is a colorless solid. The compound is one of the eight isomers ofpentyl alcohol.
Neopentyl alcohol can be prepared from the hydroperoxide of diisobutylene.[3]It can also be prepared by the reduction oftrimethylacetic acid withlithium aluminium hydride. Neopentyl alcohol was the first described in 1891 by L. Tissier, who prepared it by reduction of a mixture of trimethyl acetic acid and trimethylacetyl chloride with sodium amalgam.[4]
Neopentyl alcohol can be converted to neopentyl iodide by treatment withtriphenylphosphite/methyl iodide:[5]
