Syntheses of heteroleptic 1,8-bis(phosphino)naphthalenes and 5,6-bis(phosphino)acenaphthenes were attempted using several synthetic strategies. Reaction of aryllithium with triphenylphosphite gave ArP(OPh)2 (Ar = substituted naphthalene or acenaphthene), which was transformed into ArP(CF3)2, using a nucleophilic trifluoromethylation reaction with Me3SiCF3/CsF. The importance of the correct choice of
