The use of Rh catalysts derived from a phospholane-phosphite ligand were found to be more productive than the classic rhodium/BINAP system in enantioselective conjugate additions. These catalysts enable the use of lower amounts of aryl boronic acid in an

An amphipathic compound containing both anti-static and anti-oxidizing functional groups is composed of a hindered phenol unit, a pentaerythritol phosphite unit, a crown ether unit and a straight-chain segment unit. The synergistic effect is controlled by controlling the length of the straight-chain segment unit to regulate the distance from the hindered phenol to the pentaerythritol phosphite units, and meanwhile, the content of effective functional groups in unit mass of the compound and the compatibility between the compound and resin are also controlled. Through migration of the crown ether group, the hindered phenol unit and the phosphite unit are migrated to the surface of the resin, so that oxidization in air can be eliminated more effectively. Because the hindered phenol unit and the pentaerythritol phosphite unit have large space structures, so that the crown ether structure is prevented from falling off from the surface of the resin, thereby increasing anti-static time of the compound. The compound can be used as an anti-static and anti-oxidizing agent for polypropylene or polyethylene.
