Phthalocyanines and related compounds: XLI. Synthesis of 9,10-diphenylanthracene-2,3-dicarboxylic acid derivatives
摘要:
Derivatives of 9,10-diphenylanthracene-2,3-dicarboxylic acid were synthesized by the Diels-Alder reaction of 1,3-diphenylisobenzofuran with adducts of furan (or silvan) and the corresponding maleic (fumaric) acid derivative or with trans-cyclohex-4-ene-1,2-dicarbonitrile, followed by aromatization.
