Synthesis and structure of 1,3,6,8-tetrakis(tert-butyl)carbazole.
1,3,6,8-Tetrakis(tert-butyl)carbazole (I) was prepd. by the reaction of carbazole with Me3CCl in the presence of AlCl3. The X-ray structures of I and its di-Et ether adduct are compared. The gap formed by the tert-Bu groups in 1,8-position has been calcd. and compared with that of the supermesityl substituent.
