描述

一般說明

2-Methyl-1,5-hexadiene on mercury-photosensitized irradiation, undergoes internal cycloaddition to afford 1-methylbicyclo[2.1.1]hexane (as major product).[1] High-temperature pyrolysis of 2-methyl-1,5-hexadiene affords 1,5-hexadiene and 2,5-dimethyl-1,5-hexadiene.[2] 2-Methyl-1,5-hexadiene undergoes stereoselective and regioselective reaction with dialkylaluminum chloride (Et₂AlCl) and titanium alkoxide [Ti(OPr-i)₄, a catalyst] followed by oxidation to afford the corresponding five-membered 3-alkylcycloalkyl methanol.[3] 2-Methyl-1,5-hexadiene is formed as a major product during the condensation reaction between allyl chloride and methallyl chloride in the presence of magnesium.[4]
