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

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