Application

2,2′-Bipyrazine (bpz) can be used as a ligand to synthesize strongly oxidizing photocatalysts. Ruthenium-based homoleptic tris(bipyrazyl) complex [(Ru(bpz)32+] derived from 2,2′-bipyrazine ligand can be used as an effective photocatalyst for oxidatively induced organic transformations. For instance, [(Ru(bpz)32+] is capable of promoting radical cation mediated Diels–Alder cycloadditions, radical thiol-ene couplings, photooxygenation reactions, and [3+2] cycloaddition reactions.

Buchwald Group – Professor Product Portal

The Buchwald group has developed a series of highly active and versatile palladium precatalysts and biarylphosphine ligands used in cross-coupling reactions for the formation of C-C, C–N, C–O, C–F, C–CF3, and C–S bonds. The ligands are electron-rich, and highly tunable to provide catalyst systems with a diverse scope, high stability and reactivity. Furthermore, the new series of precatalysts are air-, moisture and thermally-stable and display good solubility in common organic solvents. The use of precatalysts ensures the efficient generation of the active catalytic species and allows one to accurately adjust the ligand:palladium ratio. The ligands, precatalysts and methodology developed in the Buchwald group are user friendly and have rendered previously difficult cross couplings reactions, much easier to achieve.

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