Abstract

Naphthalene-1, 8-diylbis (diphenylmethylium) exhibits a unique electron-transfer reduction behavior due to the close proximity of the two triarylmethyl cations, which form a CC bond while accepting two electrons, leading to 1, 1, 2, 2-tetraphenylacenaphthene. The preparation of the dication was readily accomplished under anhydrous conditions starting from a cyclic bis (triarylmethyl) ether, derived from 1, 8-dibromonaphthalene. The process ...
