Alkane elimination reactions of amino-amino-bis(phenols) H2L1-4, Salan H2L5, and methoxy-β-diimines HL6,7 with lanthanide tris(alkyl)s, Ln(CH2SiMe3)3(THF)2 (Ln = Y, Lu), respectively, afforded a series alkyl complexes 1−8 the release tetramethylsilane. Complexes 1−6 are THF-solvated mono(alkyl)s stabilized by O,N,N,O-tetradentate ligands. 1−3 5 adopt twisted octahedral geometry, whereas 4 contains tetragonal bipyramidal core. Bearing monoanionic moiety L6 (L7), complex 7 (8) is THF-free...
Abstract This Review aims at a comprehensive overview on the recent stereospecific control polymerizations by group 3 metal complexes based catalytic systems in combination with aluminum alkyls and organoborates etc. co‐catalysts. The involved monomers include styrene substituted styrenes, conjugated dienes like isoprene butadiene, their derivatives. syndio‐ iso‐selective of styrene, unmasked polar styrenes copolymerizations are summarized. factors influencing activity selectivity discussed....
The N,O-bidentate pyridyl functionalized alkoxy ligands 2-(6-methyl-2-pyridinyl)-1,1-dimethyl-1-ethanol (L1–H) and 2-(6-methyl-2-pyridinyl)-1,1-diphenyl-1-ethanol (L2–H) have been prepared by treatment of acetone benzophenone with monolithiated 2,6-lutidine. Deprotonolysis the L1–H L2–H 1 equiv MgnBu2 ZnEt2 in toluene releasing butane ethane, respectively, gave corresponding dimeric metal-monoalkyl complexes [L1MgnBu]2 (1), [L2MgnBu]2 (2), [L1ZnEt]2 (3), [L2ZnEt]2 (4). Complexes 1–4 were...
A simple, inexpensive, and convenient catalyst system consisting of supporting ligand-free MgnBu2 in combination with an alcohol, isopropanol (iPrOH), benzyl methanol (PhCH2OH), diphenylmethanol (Ph2CHOH), or triphenylmethanol (Ph3COH), generates a to promote the polymerization l-LA. In particular, binary MgnBu2/Ph2CHOH demonstrates unprecedentedly high activity presence large excess amount Ph2CHOH [OH]0/[Mg]0 ratio varying from 2 500, producing up 500 polylactide (PLA) chains per Mg center...
Abstract Development of new strategies with high antimicrobial capability against complex bacterial infections is still challenging. Herein, a three‐in‐one synergistic platform presented based on gallium–carbenicillin framework coated defect‐rich hollow TiO 2 nanoshells (H‐TiO 2− x @MOF), for simultaneous eradicating methicillin‐resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (PA) in infections, which are the two most common bacteria wounds. The metal gallium can disrupt...
Triethanolamine (TEA) reacted with 3 equiv of yttrium alkyl complex 1 bearing O,N,N,O-tetradentate Salan ligand to give a trinuclear alkoxide counterpart 2 via metathesis reaction. Complex initiated the ring-opening polymerization rac-lactide in livingness mode under mild conditions. Remarkably, was so tolerant protic TEA that various TEA-to-yttrium molar ratios ranging from 1:3 up 81:1, performed smoothly, suggesting an immortal characteristic. The resultant polylactides had variable...
A highly efficient strategy for one-pot synthesis of programmable, crystalline–amorphous stereomultiblock PLA from rac-lactide.
A highly efficient strategy for synthesizing the first biocompatible polyesters with AIE characteristics has been established via immortal ring-opening polymerizations of cyclic esters bearing nonluminophores. In process, large excess hydroxyl-modified active compound, acting as chain transfer agent, attaches to rare-earth metal catalyst rapid-reversible exchange reaction initiate polymerization. Thus, more polyester chains appear grow from one species, and fragments are incorporated into...
A series of oxophosphine (3,5-Me2Pz)2CHP(R)2O (Pz = pyrazole; R tBu (HL1), Cy (HL2)) and iminophosphine (3,5-Me2Pz)2CHP(R)2NAr (R Cy, Ar Ph (HL3); Ph, (HL4), 2,6-Me2-phenyl (HL5)) heteroscorpionate ligands were synthesized.
