Organolanthanide-mediated hydrophosphination and ethylene polymerization are coupled in a catalytic cycle to produce diphenylphosphine-terminated polyethylenes. The resulting polymers were characterized by 1H, 13C, and 31P
Addition of phosphines to alpha-olefins

, (2008/06/13)
There is disclosed an improved process for the addition of phospines to alpha-olefins at high yields and conversions. The process involves the absence of a catalyst whose residues could interfere with the utility of the product, such as n-hexyldiphenylphosphine, as a ligand. Simple thermal reaction is used at temperatures of at least 200° C., most preferably 250° C.-350° C. The pressure is preferably at least atmospheric. Preferred reactants, products, and processing conditions are also disclosed. Batch processes are exemplified and continuous processes proposed.
