Suzuki-Miyaura cross-coupling reaction of naphthyl triflate with indole boronic acids catalyzed by a recyclable polymer-supported N-heterocyclic carbene-palladium complex catalyst: Synthesis of naphthalene-linked bis-heterocycles

摘要

In this study, the Suzuki-Miyaura cross-coupling reaction of naphthyl triflate with indole boronic acids catalyzed by a recyclable polymer-supported Pd-NHC complex catalyst is presented. The polymer-supported catalyst can be reused several times retaining high activity for the transformation. The structures of all the synthesized compounds were established by elemental analysis and from their mass, ~1H-NMR, and ~(13)C-NMR spectra.
