A new, flexible route to the substituted triphenylenes has been developed which involves the preparation of terphenyls using a palladium-catalysed cross-coupling of arylzinc halides with 1,2-dihalogenobenzenes, followed by oxidative cyclisation of these terphenyl using ferric chloride.
Borner et al. (1994) studied this question.
