Intramolecular aromatic 1,5-hydrogen transfer in preparation of oxacyclic naphthalic anhydride via unusual Pschorr cyclisation

Unusual Pschorr cyclisation via naphthyl radical-induced intramolecular aromatic 1,5-hydrogen transfer using the corresponding diazonium salts as starting materials gave five- and six-membered oxacyclic-fused naphthalic anhydride isomers.

The quest for highly fluorescent chromophores: Evaluation of 1H,3H-isochromeno[6,5,4-mna]xanthene-1,3-dione (CXD)

Photophysical properties of the strongly fluorescent dye, 1H,3H-isochromeno[6,5,4-mna]xanthene-1,3-dione (CXD), are reported. This highly planar, rigid dye absorbs at around 420 nm, which is ideal for excitation with a blue laser diode, and is extremely stable towards prolonged illumination. Under near-UV excitation, the dye readily sensitises free-radical polymerisation, forming a plastic film with excellent optical transparency. Weakly structured emission is observed with a small Stokes' shift and remains essentially insensitive to changes in solvent polarity. For example, in tetrahydrofuran the fluorescence quantum yield is 0.96 while the excited-singlet state lifetime is 7.4 ns. Quantum chemical calculations provide further insight into the electronic nature of the dye in solution.

Synthesis of a novel oxoxanthenoisoquinoline via a palladium-catalysed cross-coupling reaction; as a fluorophore

Suzuki cross-coupling of a bromoaromatic anhydride with 2-methoxyboronic acid afforded a novel oxoxanthenoisoquinoline. Subsequent coupling with 2,3,4,6-tetra-O-acetyl-D-galactose-1,3-diyl phosphate gave a fluorophore. (C) 2000 Elsevier Science Ltd.
