Document Type and Number:
Japanese Patent JP5283807
Kind Code:
B2
Abstract:
This invention relates to processes for making phosphorus compounds R 2 P-X-PR 2 , R 2 P-M, R 2 P-L and R 3 P, and the novel cation R 2 P + (L)-X-P + (L)R 2 , where R represents an optionally substituted hydrocarbyl group, X represents a bridging group, L represents a leaving group and M represents an alkali metal atom. The invention relates further to a process for making a compound R 2 P-L from a compound R-H via a new process for making the compound R-Li followed by its reaction with a compound Hal 2 P-L. The compound R 2 P-X-PR 2 is a ligand suitable for making catalysts for copolymerizing carbon monoxide and an olefinically unsaturated compound.
