WebPhosphine ligands are the most significant class of ligands for cross-coupling because of the alterability of their electronic and steric properties. Ligands play a key role in stabilizing and activating the central metal atom and are used in reactions, such as transition metal catalyzed cross-coupling. Research has focused on the development ... WebGeneral description. It contains a set of seven phosphine ligands with varying steric and electronic properties useful for rapid screening of catalysis conditions. It is in sampler format with individual components packaged for multiple experiments and mini scale-up. The cost of the kit is less than the total cost of individual components.
