The application of 2,4-dibromo-2,4-dimethyl-pentane 5 has been tested with respect to the attempted synthesis of 1,1,3,3-tetra-methyl-tetrahydropentalene 3. Addition of aqueous hydrobromic acid to a solution of 2,4-dimethyl-1,3-pentadiene 4 in ether gives 4-isopropenyl-1,3,3,5,5-pentamethyl-cyclohexene 10 in an excellent yield and in high GC-purity. The temperature-dependent 13C-NMR-spectra of compound 10 are discussed.
