  Metal and Ligand-Substituent Effects in the Immortal Polymerization ofrac-Lactide with Li, Na, and K Phenoxo-imine Complexes

  摘要：

  A series of lithium, sodium, and potassium complexes with phenoxo-imine ligands M[(O-2-(RN=CH)-C6H4] [R = C6H5; 2-(BuC6H5)-Bu-t; 2,6-(Pr2C6H3)-Pr-i] and [O-2-(RN=CH)-4,6-(Bu2C6H4)-Bu-t] [R = C6H5; 2-(BuC6H5)-Bu-t; 2,6-(Pr2C6H3)-Pr-i] 1-3(a-f) have been synthesized. The molecular structures in the solid state of some of these complexes have been determined by X-ray diffraction. These compounds show different nuclearities and geometries around the metal center depending on the nature and the pocket of the ligand substituents. Of particular interest is the structure of compound 3e, being the first example of a potassium cubane complex obtained with this kind of ligand. The structural behavior in solution has also been studied by diffusion-ordered NMR spectroscopy (DOSY), showing a direct correlation between aggregation behavior and polymerization activity. Compounds 1-3(a-f) are extremely active catalysts in the ring-opening polymerization (ROP) of rac-lactide, achieving conversions of 100% in less than 1 min and heterorich-PLA that is modified by the metal atom and the ligand substituents. BnOH was used as co-initiator, and the presence of large amounts of the alcohol produces the immortal polymerization of rac-lactide in a more controlled process. Stoichiometric reactions involving the catalysts, BnOH, and lactide demonstrated an activated monomer mechanism for the polymerization of rac-lactide.

  The salts were reacted with thorium tetrachloride at room temperature to obtain the corresponding (ONOO)ThCl2 (5) and (ONNO)ThCl2 (6) complexes.However, ThCl4 and UCl4 react with (3) at higher temperatures to give the corresponding isomorphous homoleptic complexes (ONOO)2Th (7) and (ONOO)2U (8).We have also synthesized and characterized a thorium salicylaldiminato complex L3ThCl (11) [L=(C6H5)NCH(2-O-C6H2-Bu2t-3

  螯合氨基双酚配体（ONOO）H 2（1）[ONOO = MeO N CH2-（2-O-C6H2-Bu2t-3,5）} 2]与（ONNO）H 2（2）[ONNO =带有过量NaH的Me2N N -（2-O- -Bu2t-3,5）} 2]定量给出相应的双钠盐3和4。这些盐在室温下与四氯化th反应，得到相应的（ONOO）ThCl 2（5）和（ONNO）ThCl 2（6）complexes.However，ThCl 4和UCL 4与（反应3）在更高的温度下得到相应的同构均纯络合物（ONOO）2 Th（7）和（ONOO）2 U（8）。我们还合成并表征了a水杨醛亚氨基络合物L 3 ThCl（11）[L =（C6H5 ）NCH（2-O- -Bu2t-3,5）] ，以研究桥联配体对分子结构的影响。
