Synthesis method of hydroquinine(anthraquinone-1,4-diyl)diether

The invention discloses a synthetic method of hydroquinine(anthraquinone-1,4-diyl)diether (CAS: 176097-24-8) as shown in a formula (f), which comprises the following steps: by using phthalic anhydrideas a raw material, carrying out Friedel-Crafts reaction and dehydration cyclization reaction to obtain a compound c; and carrying out a coupling reaction on the compound c and dihydroquinine to obtain the hydroquinine(anthraquinone-1,4-diyl)diether. The synthesis method has the advantages of short reaction route, high yield, simplicity and convenience in operation, low cost, suitability for industrial production and the like.

Synthesis of 6,13-difluoropentacene

6,13-Difluoropentacene was synthesized from 1,4-difluorobenzene. Friedel-Crafts annulation of the latter with phthalic anhydride and subsequent reduction of the anthraquinone gave 1,4-difluoroanthracene. After ortho-lithiation and reaction with phthalic anhydride a carboxylic acid was obtained whose Friedel-Crafts acylation and subsequent reductive removal of the oxygen-functionalities resulted in the formation of the target compound. The HOMO-LUMO gap of 6,13-difluoropentacene was determined via UV-vis spectroscopy and compared to other fluorinated pentacenes.
