商品

A variety of transition-metal catalysts for the Suzuki coupling reaction are now available in our catalog. The majority of these catalysts are palladium- and nickelbased, typically utilizing phosphine-derived ligands.

The Heck reaction is the palladium catalyzed cross-coupling reaction between alkenes and aryl or vinyl halides (or triflates) to afford substituted alkenes.
