| | 2,5-Dimethyl-2,4-hexadiene Usage And Synthesis |
| Chemical Properties | clear colourless liquid | | Uses | 2,5-Dimethyl-2,4-hexadiene may be used in the synthesis of (+)-trans-(1R,3R)-chrysanthemic acid methyl ester. | | Uses | 2,5-dimethyl-2,4-hexadiene is a volatile alkyl compound present in tobacco smoke. It is used as a potential biomarker in breath for prediction of lung cancer.
| | Definition | ChEBI: 2,5-Dimethyl-2,4-hexadiene is an alkadiene. | | General Description | 2,5-Dimethyl-2,4-hexadiene is an electron-rich alkene. It induces photodechlorination of 9,10-dichloroanthracene and its mechanism has been investigated. Asymmetric cyclopropanation of 2,5-dimethyl-2,4-hexadiene with tert-butyl diazoacetate catalyzed by the new copper-bisoxazoline complex has been reported. 2,5-Dimethyl-2,4-hexadiene has been investigated as a singlet oxygen acceptor in various solvents. Mechanism of addition reaction of aromatic and aliphatic thiols with 2,5-dimethyl-2,4-hexadiene has been investigated. | | Purification Methods | Distil, then repeatedly fractionally crystallise it by partial freezing. Immediately before use, the diene is passed through a column containing Woelm silica gel (activity I) and Woelm alumina (neutral) in separate layers. [Beilstein 1 IV 1043.] |
