Gold-Catalyzed Annulation of 1,8-Dialkynylnaphthalenes: Synthesis and Photoelectric Properties of Indenophenalene-Based Derivatives

A simple gold-catalyzed annulation of 1,8-dialkynylnaphthalenes utilizing a cationic gold catalyst was developed. Such a peri-position of two alkynyl substituents has not been studied in gold catalysis before. Dependent on the substrate, the reactions either follow a mechanism involving vinyl cation intermediates or involve a dual gold catalysis mechanism which in an initial 6-endo-dig-cyclization generates gold(I) vinylidene intermediates that are able to insert into C?H bonds. Indenophenalene derivatives were obtained in moderate to high yields. In addition, the bidirectional gold-catalyzed annulation of tetraynes provided even larger conjugated π-systems. The optoelectronic properties of the products were also investigated.

Synthesis and photoelectric properties of novel indeno[2,1-a]phenalene- based derivatives

A series of novel indeno[2,1-a]phenalene derivatives 4a-j including electron-donating or electron-withdrawing groups were prepared by Pd-catalyzed Sonogashira-Hagihara reaction of 7-iodo-12-phenylindeno[2,1-a]phenalene with various arylacetylene. Photoele

Palladium-catalyzed synthesis of 7,9-diaryl-8 H-acenaphtho[1,2-c]pyrroles and their application in explosives detection

Making sensors of pyrroles: 7,9-Diarenyl-8H-acenaphtho[1,2-c]pyrroles were efficiently constructed by a palladium-catalyzed bicyclization of 1,8-diarenynyl naphthalenes and primary amines under air conditions (see scheme). The synthesized 8H-acenaphtho[1,
