What is (R)-SEGPHOS?
The Uses of (R)-SEGPHOS
(R)-(+)-SEGPHOS? is a chelating ligand used to prepare coordination complex catalysts, such as its use in Pd catalysts for the enantioselective addition of diesters to 3,3-difluoropropenes, and in the Ni-based catalyst for the asymmetric propargylic amination of propargylic carbonates with an internal alkyne group.
