Synthesis of Corannulene and Alkyl Derivatives of Corannulene

摘要: Synthesis of corannulene and alkyl derivatives has been accomplished using solution-phase chemistry. The key step in the synthesis is coupling benzylic bromides 1,6,7,10-tetraalkylfluoranthene by low-valent titanium to construct nucleus. use represents a viable alternative flash vacuum pyrolysis methods previously developed. Corannulene (1), methylcorannulene (8), three different dimethylcorannulenes (2, 3, 5), two tetramethylcorannulenes (4, 6), acecorannulylene (7), C5h symmetric pentamethylcorannulene (9), decamethylcorannulene (10) have prepared carbon−carbon chemistry halogen for exchange mediated trimethylaluminum catalytic nickel salts.
