General description
2,7-Dihydroxynaphthalene is reported to undergo condensation with the malonaldehyde tetramethyl acetal, to afford 8,16-methano-16H-dinaphtho[2,1-d:1′,2′-g]-[1,3]dioxocin-2,14-diol.
Application
2,7-Dihydroxynaphthalene (2,7-DHN) may be used in the synthesis of following:
- osmium nanoparticles (NPs) having different morphologies like aggregated clusters, chain-like networks and small spheres
- ionomers having aromatic polymer backbones with pendant 2-sulfobenzoyl side chains, via nucleophilic aromatic substitution reactions
- several new banana-shaped mesogens
- novel dicyanate ester resin containing naphthalene ring (DNCY)
