The sequentialimination and intramolecularpalladium-catalyzeddirectarylation of thiophene-3-carbaldehyde or furan-3-carbaldehyde with 2-haloanilines provided a one-pot access to furo- or thienoquinolines in high yields with H2O and HBr as the major waste. Both electron-withdrawing and -donating substituents on the 2-haloaniline derivatives were tolerated. These furo- or thienoquinoline derivatives

A novel and efficient palladium-catalyseddirect di-heteroarylation of 1,2-dichloroperfluorocyclopentene with a variety of heteroarenes is reported, giving rise to 1,2-di(heteroaryl)ylperfluorocyclopentene photochromic compounds. The reaction proceeds with thiazoles, thiophenes or furan derivatives and tolerates various substituents.
