2-Methyl and 3-methylterrylenes have been obtained by Suzuki coupling of 3-bromoperylene and corresponding methylnaphthylboronic acids or esters, giving methylnaphthylperylene isomers, followed by Scholl cyclodehydrogenation; the latter reaction gave also the other cyclodehydrogenation isomers 10(respectively, 9-) methylbenzo[4,5]indeno[1,2,3-cd]perylene.
