The synthesis of anthracene, and dipyridine salts as cations for DMIT complexes

The synthesis of a series of cations for the preparation of [Ni(dmit)2]2 complexes is described. These cations are a series of 9,10-disubstituted anthracene derivatives with phosphane or alkylamine sustituents. Metal catalysed coupling reactions were used to prepare the 9,10-ethynylanthracene derivatives, one of which was subsequently methylated, using iodomethane as methylating reagent, to form cations for [Ni(dmit)2]2−salts. A range of salts were prepared using ferrocene and anthracene-based cations with [Ni(dmit)2]2− as the dianion.
