Description

General description

ImPy-Trip-IPr* is a member of a class of biaryl NHC ligands utilizing sterics to facilitate a well-defined L-shaped NHC. The unique shape allows for the development of cross-coupling reactions not possible with other NHC ligands, as well as an improvement in catalytic efficiency with many existing methods. Readily forms complexes with Pd, as well as Au, Cu, Rh, and other metals.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.
