Naphthalic and bis(naphthalic) anhydrides with acetylene groups

Article abstract of DOI:10.1007/BF00702400

Cross-coupling Pd-catalyzed reaction of readily available 4-bromo-1,8-naphthalic anhydride with acetylene or its derivatives result in naphthalic and bis(naphthalic) anhydrides with acetylene groups.The temperature ranges of the cross-linking of the acety
