Organosilanes for Cross-coupling

Over the past several years, Pd-catalyzed cross-coupling of silicon compounds has rapidly gained acceptance as a suitable alternative to more commonly known methods such as: Stille (Sn), Kumada (Mg), Suzuki (B), and Negishi (Zn) cross-couplings.

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