• Bifunctional Catalysis Prevents Inhibition in Reversible-Deactivation Ring-Opening Copolymerizations of Epoxides and Cyclic Anhydrides

  Reversible-deactivation chain transfer is a viable strategy to increase the catalytic efficiency of ring-opening polymerizations, such as the alternating copolymerization of epoxides and cyclic anhydrides. In conjunction with the catalyst, protic chain transfer agents (CTAs) initiate polymerization and facilitate rapid proton transfer between active and dormant chains. Functional-group-tolerant Lewis

  可逆失活链转移是提高开环聚合催化效率的可行策略，例如环氧化物和环酐的交替共聚。与催化剂一起，质子链转移剂 (CTA) 引发聚合并促进活性链和休眠链之间的快速质子转移。因此，需要耐官能团的路易斯酸催化剂才能成功地将质子 CTA 应用于可逆失活开环共聚 (RD-ROCOP)，但当与质子 CTA 一起使用时，主要的二元路易斯酸催化剂/亲核助催化剂体系的聚合速率较低. 对抑制途径的新机制洞察表明，醇链末端与环氧化物竞争与路易斯酸的结合，并与阴离子链末端形成氢键以阻止环氧化物开环。我们报告说，双功能氨基环丙烯铝盐复合物在质子功能存在的情况下保持出色的活性，即使在高 CTA 浓度下也表现出对这些抑制途径的弹性。我们在双功能 ROCOP 系统中应用可逆失活链转移，以展示精确的分子量控制、CTA 官能团范围和可访问的聚合物结构。即使在高 CTA 浓度下，也表现出对这些抑制途径的弹性。我们在双功能 ROCOP

  synthesis of robust and air‐stable [Al(Salophen)] derivatives capable of undergoing spontaneous self‐assembly at the graphite/solution interface forming highly‐ordered nanopatterns. The new synthetic approach relies on the use of [MeAlIII(Salophen)] as a building unit to introduce, via a simple acid/base reaction with functionalized acidic phenol derivatives, selected frameworks integrating multiple functions

  Salophens和Salens是席夫碱，是通过将两当量的水杨醛分别与1,2-苯二胺或脂族二胺缩合生成的。两种配体已被广泛用作配位化学和催化的关键组成部分。特别地，它们的金属络合物以高产率和高选择性被广泛用于各种催化转化。通过苯酚单元的修饰，可以调节Salophen和Salen的位阻和电子性能。在水杨醛中引入长脂肪族链可用于促进其自组装成固体表面上的有序超分子结构。在此处，我们报道了一种新的方法，可以轻松合成能够在石墨/溶液界面处自发自组装并形成高度有序的纳米图案的坚固且稳定的[Al（Salophen）]衍生物。新的合成方法依赖于[MeAlIII（Salophen）]作为构建单元，通过与功能化的酸性酚衍生物的简单酸/碱反应，引入结合了多种功能的选定框架，以进行有效的表面装饰。固/液界面处的STM成像使监测有序超分子结构的形成成为可能。此外，通过循环伏安法揭示了在溶液中和表面上被二茂铁单元官

  The unsymmetrical salphen ligand (3,5-Bu-t-1-OH- C6H2) CH=N-C6H4-N,=CH (3-Ph-1-OH-C6H3) (tBu-PuLH2,) was designed and synthesized to support aluminum complexes. Its symmetric analogues, (3,5-Bu-t-1-OH-C6H2)CH=N-C6H4-N=CH(3,5-Bu-t-1-OH-C6H2) ((LH2)-L-tBu) and (3-Ph-1-OH-C6H3)CH=N-C6H4-N=CH(3-Ph-1-OH-C6H3) (PhLH,), were also explored and compared. The methane elimination reactions between ligands and AlMe3 resulted in formation of ah tBu-PhLAlMe (1),(LAlMe)-L-tBu (2), and (LAlMe)-L-Ph (3) in high yields, which were characterized by elemental analysis, H-1 and C-13 NMR. The coordination geometries of unsymmetrical and symmetric ligands in 1 and 2 were studied by X-ray diffractions, which revealed a five coordinated distorted square-pyramidal geometry around Al centers. The aluminum methyl compounds 1-3 reacted with BnOH at 70 degrees C to give tBu-PhLAlOBn (4), (LAlOBn)-L-tBu (5), and (LAlOBn)-L-Ph (6), respectively, which existed as monometallic species in solution. as indicated by NMR studies. However, the aluminum isopropoxide prepared by the reaction of tBu-PhLH2, with 1 equiv of Al((OPr)-Pr-i)(3) contained three species, one monometallic (tBu-PhLAlOPr)-Pr-i (7) and two bridged dimers,mu-O-2-(cis-(tPu-PhLAlOPr)-Pr-i)(2) (8) and mu-O-2-(trans-(tBu-PhLAlOPr)-Pr-i)(2), (9). The catalytic performances of unsymmetrical 4 for the ring-opening polymerization of racemic lactide (rac-LA) were preliminarily studied and compared to those of symmetric 5 and 6.

  When the reagents LAlMe (L = N,N'-(alkylene or arylene) bis(3,5-di-tert-butyl)salicylidenelmine (alkylene = ethylene (Salen(tBu)) (1), propylene (Salpen(tBu)) (2), and butylene (Salben tBu)) (3); arylene = phenylene (Salophen(tBu) (4), 3,4-dimethylphenylene (Salomphen(tBu) (5)) are combined with Ph(H)P(O)OH in tetrahydrofuran (thf) the unique aluminophosphinate compounds, [L(tBu)AlO2P(H)Ph}](n) with L, n = Salen, infinity (6), Salpen, 2 (7), Salben, 2 (8),. Salophen, infinity (9) and Salomphen, infinity (10) are produced. The yields for the latter two reactions are low, and it was subsequently found that the unique thf-coupled compounds appear in the thf filtrates of the original reaction mixture. These compounds are, [L-thf(tBu)AlO2P(H)Ph}](2), L = Salophen (13) and Salomphen (14). The thf connects through an a-carbon to only one of the two possible imine carbons of the ligand. While trying to determine how this coupling proceeds,,the six-coordinate, solution-state species LAlMe(thf) (L = Salophen (11) and Salomphen (12) were discovered and implicated as intermediates. All of the compounds are characterized by melting point, NMR, IR, and-X-ray analyses for 5-8, 13, and 14, A possible mechanism for the thf coupling event is presented.
