JosiPhos CyPF-tBu and palladium give catalyst for alkoxylation of activated heteroaryl halides with primary, secondary, and tertiary alcohols

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
