Living 3,4‐(Co)Polymerization of Isoprene/Myrcene and One‐Pot Synthesis of a Polyisoprene Blend Catalyzed by Binuclear Rare‐Earth Metal Amidinate Complexes
Four homodinuclear rare earth metal (RE) complexes 1-4 bearing a multidentate diglycolamine-bridged bis(phenolate) ligand were synthesized. In addition, seven heterobimetallic RE-Zn complexes 5-11 were prepared through a one-pot strategy. In...
One-pot salt metathesis reaction of LnCl3, [2,6-iPr2C6H3N(SiMe3)]Li and LiN(SiHMe2)2 in 1 : 1 : 2 molar ratio gave [2,6-iPr2C6H3N(SiMe3)]Ln[N(SiHMe2)2]2(THF) (Ln = Y, Lu, La), which were highly active for cis-1,4 polymerization of isoprene in the presence of [Ph3C][B(C6F5)4] and AliBu3.
All solid solutions (EuxY1−x-PTC, x = 0.013–0.82) are isomorphic to Eu-PTC, but different from Y-PTC, and show phase selectivity as well as excitation wavelength dependent emission.
