Biomass-derived 2,5-furandicarboxylic acid was valorized by conversion to 1,4-naphthalenedicarboxylic acid via benzyne-cycloaddition and reductive aromatization in 66% overall yield (four steps). Two novel bicyclic intermediates were isolated in 80% and 98% yield. These advances diversify the potential end uses of renewable terephalic acid analogs and other furanics available from cellulose biorefinery.
New Dyes from Naphthostyril-5-carboxylic Acid: Synthesis of 6,12-Anthanthrenedione-3,4,9,10-tetracarboxylic Diimides, Naphthostyril-5,6-dicarboximides and 1-Amino-4-arylaminonaphthalene-5,8-dicarboxylic Bislactams

The novel vat dyes 6,12-anthanthrenedione-3,4,9,10-tetracarboxylic diimides (XIa-c) and the disperse dyes, naphthostyril-5,6-dicarboximides (XVIIIa-f) and bislactams (XIXa-d) have been synthesised from a common intermediate, naphthostyril-5-carboxylic acid (V).An improved method has also been developed for the synthesis of V.
Process for the preparation of naphthalene-1,4-dicarboxylic acid

, (2008/06/13)
A process for the preparation of naphthalene-1,4-dicarboxylic acid, which comprises reacting 1,4-dihalogenonaphthalene with at least 2 moles of copper-I cyanide per mole of dihalogenonaphthalene in a polar, aprotic solvent and subjecting the copper salt complex of 1,4-dicyanonaphthalene thus obtained to alkaline hydrolysis.
