Phosphorus ligands, polymeric supports

The phosphination procedure (18) was applied for functionalization of brominated beads and membranes. This same procedure was also the final step in the sequence for the attachment of the asymmetric phosphorus-containing ligand DIOP to the polymeric support. The phosphination involved the reaction of lithium diphenylphosphide prepared by a literature route (19) with the -Br groups.
