2,5-Dimethyl-2,5-hexanediol on heteropoly acid catalyzed dehydration yields cyclic ethers via stereospecific intramolecular SN2 mechanism. It reacts with nitriles in concentrated sulfuric acid to yield Δ1-pyrrolines.
D 2733 (OTTO) 2,5-Dimethyl-2,5-hexanediol, 97% Cas 110-03-2 - used in the synthesis of six- and seven-membered heterocyclic boron compounds containing intramolecular N-B bond.
