The Baran Group works with Sigma-Aldrich in providing a portfolio of zinc-based reagents promoting difluoromethylation, trifluoromethylation, trifluoroethylation and isopropylation of aryl and heteroaryl motifs. Baran’s lab has also helped introduce a portable desaturase (Tz0Cl), which promotes the installation of alcohol and amine groups and leaves behind a highly useful tosyl group for further transformations.

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