  • The synthesis of 4′-aryl substituted terpyridines by Suzuki cross-coupling reactions: substituent effects on ligand fluorescence
    作者:Wendy Goodall、Kerstin Wild、Kathryn J. Arm、J. A. Gareth Williams
    DOI:10.1039/b205330f
    日期:——
    Several 4′-aryl-substituted 2,2′:6′,2″-terpyridines (tpy-C6H4R) have been prepared by palladium-catalysed cross-coupling of 4′-bromoterpyridine or 4′-triflate-terpyridine (triflate = trifluoromethylsulfonyloxy) with aryl boronic acids or esters, RC6H4B(OR′)2 (R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2). The new ligand 4′-mesitylterpyridine (mesityl = 2,4,6-trimethylphenyl) was prepared in the same way. Similarly, 4′-bromophenylterpyridine (tpy-ϕ-Br) has been cross-coupled with aryl halides to generate several new biaryl-substituted terpyridines (tpy-ϕ-C6H4R where R = H, p-CN, NMe2, NPh2), together with two related compounds with pendent 3- or 4-pyridyl groups (tpy-ϕ-C6H4-py). For selected compounds, the alternative coupling strategy of reaction of a terpyridine-4-boronate or terpyridine-4-phenylboronate with the appropriate aryl halide has also been investigated (e.g. to prepare tpy-ϕ-C6H4NO2), but was generally found to be less satisfactory. All of the compounds are fluorescent in the UV region of the spectrum, the biaryl-substituted compounds being only slightly red-shifted compared to the monoaryl systems, but with the further red-shift that accompanies protonation being more significant for the former. Fluorescence lifetimes in solution are in the range 1–5 ns. The emission spectra of the aminobiphenyl-substituted compounds (tpy-ϕ-C6H4NR″2, where R″ = Me or Ph) display a large red-shift with increasing solvent polarity, suggesting the involvement of an intramolecular charge transfer state, as found previously for the two analogues omitting the phenyl ring (tpy-C6H4NR″2). In contrast to the latter, however, protonation or binding of a Lewis acidic metal ion to the aminobiphenyl compounds serves to quench almost completely their emission.
    通过钯催化的交叉偶联反应,制备了几种4′-芳基取代的2,2′:6′,2″-三联吡啶(tpy-C6H4R),涉及4′-溴三联吡啶或4′-三氟甲磺酸酯三联吡啶(triflate = 三氟甲磺酰氧基)与芳基硼酸或硼酸酯的反应,RC6H4B(OR′)2(R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2)。新配体4′-三甲基苯基三联吡啶(mesityl = 2,4,6-三甲基苯基)也通过相同方法制备。类似地,4′-溴苯基三联吡啶(tpy-Φ-Br)已与芳基卤化物交叉偶联,生成了几种新的双芳基取代三联吡啶(tpy-Φ-C6H4R,其中R = H, p-CN, NMe2, NPh2),以及两种含有3-或4-吡啶基侧链的相关化合物(tpy-Φ-C6H4-py)。对于选定的化合物,还研究了替代的偶联策略,即反应一个三联吡啶-4-硼酸酯或三联吡啶-4-苯基硼酸酯与适当的芳基卤化物(例如制备tpy-Φ-C6H4NO2),但通常发现效果较差。所有化合物在紫外区域都有荧光发射,双芳基取代的化合物相比于单芳基系统仅有轻微的红移,但其伴随质子化产生的进一步红移对前者更为显著。溶液中的荧光寿命在1~5纳秒范围内。氨基联苯取代化合物的发射光谱(tpy-Φ-C6H4NR″2,其中R″ = Me或Ph)随着溶剂极性的增加显示出较大的红移,表明存在分子内电荷转移态,这与先前报道的两种省略苯环的类似物(tpy-C6H4NR″2)一致。然而,与后者不同,氨基联苯化合物在质子化或与路易斯酸性金属离子结合时,其发射几乎完全淬灭。
  • Synthesis of Hindered Anilines: Copper-Catalyzed Electrophilic Amination of Aryl Boronic Esters
    作者:Richard P. Rucker、Aaron M. Whittaker、Hester Dang、Gojko Lalic
    DOI:10.1002/anie.201200480
    日期:2012.4.16
    No longer a hindrance: Copper‐catalyzed electrophilic amination of aryl boronic esters is accomplished under mild reaction conditions using 2.5–5.0 mol % of a catalyst derived from copper tert‐butoxide and Xantphos ligand (see scheme). The reaction tolerates a wide range of functional groups and can be used to prepare some of the most hindered anilines made to date.
    不再是障碍:芳基硼酸酯的铜催化亲电胺化反应可在温和的反应条件下,使用2.5-5.0 mol%的叔丁醇铜和Xantphos配体衍生的催化剂完成(参见方案)。该反应可耐受各种官能团,可用于制备迄今为止制备的某些受阻最大的苯胺。
  • pH-Responsive N-heterocyclic carbene copper(i) complexes: syntheses and recoverable applications in the carboxylation of arylboronic esters and benzoxazole with carbon dioxide

    developed as a green and novel strategy for homogeneous catalyst recycling, which has been successfully applied to the Cu-NHC-catalyzed carboxylation of organoboronic esters and benzoxazole with carbon dioxide. Additionally, the present strategy could also be extended to the Ag-NHC-catalyzed carboxylation of terminal alkyne. The tertiary amine-functionalized catalysts could be used for at least four

  • Enantioselective Synthesis of Chiral Indane Derivatives by Rhodium-Catalyzed Addition of Arylboron Reagents to Substituted Indenes
    作者:Moeko Umeda、Hikaru Noguchi、Takahiro Nishimura
    DOI:10.1021/acs.orglett.0c03651
    日期:2020.12.18
    asymmetric addition of arylboron reagents to indene derivatives proceeded to give 2-arylindanes in good yields with high enantioselectivity. Deuterium-labeling experiments indicated that the present reaction involved a 1,4-Rh shift from an initially formed benzylrhodium to an arylrhodium intermediate before protonation leading to the corresponding addition product. The asymmetric addition was also successful

  • Two-Step, One-Pot Ni-Catalyzed Neopentylglycolborylation and Complementary Pd/Ni-Catalyzed Cross-Coupling with Aryl Halides, Mesylates, and Tosylates
    作者:Daniela A. Wilson、Christopher J. Wilson、Brad M. Rosen、Virgil Percec
    DOI:10.1021/ol801972f
    日期:2008.11.6
    Two-step, one-pot neopentylglycolborylation of aryl iodides and bromides catalyzed by NiCl2(dppe) and NiCl2(dppp) is reported. Electron-rich and electron-deficient aryl neopentylglycolboronates were efficiently cross-coupled with aryl iodides, bromides, chlorides, mesylates, and tosylates by exploiting complementary Pd/Ni and Ni/Ni catalysis. The borylation route was further extended to a three-step
    据报道,NiCl2(dppe)和NiCl2(dppp)催化芳基碘和溴化物的两步一锅新戊基乙二醇化反应。通过利用互补的Pd / Ni和Ni / Ni催化作用,富电子和缺电子的芳基新戊基乙二醇硼酸酯可以有效地与芳基碘,溴化物,氯化物,甲磺酸酯和甲苯磺酸酯交联。硼化途径通过原位镍催化的硼化和Pd介导的交叉偶联进一步扩展为三步一锅合成联芳基。
