Room temperature aerobic Suzuki cross-coupling reactions in DMF/water mixture using zeolite confined palladium(0) nanoclusters as efficient and recyclable catalyst

Herein we report the use of zeolite confined palladium(0) nanoclusters as efficient and recyclable catalyst for Suzuki cross-coupling reactions of aryl bromides with phenylboronic acid. Zeolite confined palladium(0) nanoclusters are highly active catalyst for the Suzuki cross-coupling reactions under mild conditions (room temperature, in air) in DMF/water (1:9) mixture. A variety of aryl bromides undergo Suzuki cross-coupling with phenylboronic acid with quantitative GC yields of biaryl derivatives. Recycling experiments showed that zeolite confined palladium(0) nanoclusters can be used as recyclable catalyst in the Suzuki cross-coupling reactions.

Zeolite confined palladium(0) nanoclusters are found to be efficient and recyclable catalysts for the Suzuki cross-coupling reactions of aryl bromides with phenylboronic acid under mild conditions (at room temperature and in air) in DMF/water (1:9) mixture, giving biaryl derivatives in high yield as determined by GC.Figure optionsDownload high-quality image (35 K)Download as PowerPoint slide
