Synthesis and fluorescence of 3,4,6,7,8,9-hexaphenyl-1H-benzo[g]isochromen-1-one

Publication date: Available online 27 December 2017 Source:Journal of Organometallic Chemistry Author(s): Dmitry A. Loginov, Alexander P. Molotkov, Nikolay E. Shepel Highly step- and atom-economic synthetic route to 3,4,6,7,8,9-hexaphenyl-1H-benzo[g]isochromen-1-one (1) based on the rhodium catalyzed reaction of terephthalic acid with diphenylacetylene was developed. The best catalytic system for this reaction is [CpRhI2]n/Cu(OAc)2. Compound 1 shows fluorescent properties with a strong Stokes shift. Graphical abstract
