1,3,5,7-TETRAALKYLADAMANTANES AS NOVEL ADAMANTANE DERIVATIVES, METHOD FOR SYNTHESIS OF 1,3,5,7-TETRAALKYLADAMANTANE AND MODIFICATION OF POLYALKYLADAMANTANE MIXTURES Russian patent published in 2011 - IPC C07C13/615 C07C2/68 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for synthesis for 1,3,5,7-tetraalkyladamantane of general formula where R¹=R²=R³=R⁴=Et; R¹=R²=R³=R⁴=n-Pr; R¹=R⁴=Me, R³=R⁴=Et; R¹=R²=Me, R³=R⁴=n-Pr; R¹=R²=R³=n-Pr, as well as polyalkyladamantane mixtures in the presence of electrophilic catalysts, characterised by that adamantane, 1,3-dimethyladamantane or a mixture of polyalkyladamantanes with a total of 11-20 carbon atoms is alkylated with C_nH_2n olefins, where n=2 or 3, in the presence of a catalyst system with gross formula AlX₃·C_kHal_r, where X=CI, Hal=Br, k=0, r=2, or X=Br, Hal=CI, k=1, r=4, and the process is carried out in a CH₂X₂ (X=Cl, Br) solution at 15 - 25°C for 2-3 hours in molar ratio [adamantane]:[catalyst] = (15-10):1. The invention also relates to novel compounds EFFECT: high output and selectivity of desired compounds.
