1,3,5,7-TETRAALKYLADAMANTANES AS NOVEL ADAMANTANE DERIVATIVES, METHOD FOR SYNTHESIS OF 1,3,5,7-TETRAALKYLADAMANTANE AND MODIFICATION OF POLYALKYLADAMANTANE MIXTURES

摘要

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 CnH2n olefins, where n=2 or 3, in the presence of a catalyst system with gross formula AlX3CkHalr, 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 - 25C 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. ^ 2 cl, 32 ex, 6 tbl
