Well-defined phosphate yttrium dialkyl complexes for catalytic stereo-controllable 1,4-polymerization of isoprene
文献摘要：
Oxygen ligation is envisioned to provide a stable and distinctive coordination environment to the strongly oxophilic rare-earth metals.However,the well-defined dialkyl complexes bearing oxyanion ancillary lig-and had been rarely addressed for the instability of the complexes and the shortage of easily available ligands.Herein,we report the synthesis of phosphate ligated dialkyl yttrium complexes(PYR2)featuring a high stability and a tunable ligand.Treated with the borate reagent,the phosphate yttrium complex displays high activity and selectivity in the catalytic cis-1,4-polymerization of isoprene(up to 96.5％).Fur-thermore,using AlMe3 as an additive,the stereoselectivity switches to trans-1,4-polymerization(up to 92.0％).
