Abstract

The hydroarylation of alkynes can be successfully conducted in 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4) in the presence of the [(E, E, E)-1,6,11-tris(p-toluenesulfonyl)-1,6,11-triazacyclopentadeca-3,8, 13-triene]Pd(0) complex. The catalytic ionic solution can be recycled for reuse in subsequent reaction runs. The procedure has been applied to the preparation of 3-arylquinolines through a domino hydroarylation/cyclization process. © 2002 Elsevier Science Ltd. All rights reserved.
