A safe and efficient protocol for the synthesis of aryl sulfinates from arenes and 1,4-diazabicyclo[2,2,2]octane bis(sulfur dioxide) (DABSO) under mild conditions is described. Through in situ infrared spectroscopic studies, a plausible mechanism for the sulfination reaction is proposed as well. 相似文献

Thanks to the dissolution of bulk carbon nitride (CN), a heterojunction of CN and sulfur-doped CN was constructed via a solution-based processing way, which led to a more homogeneous composite and an improved photocatalytic H2 production activity up to 230% with respect to that by conventional impregnating. 相似文献

The garnet electrolyte presents poor wettability with Li metal, resulting in an extremely large interfacial impedance and drastic growth of Li dendrites. Herein, a novel ultra‐stable conductive composite interface (CCI) consisting of LiySn alloy and Li3N is constructed in situ between Li6.4La3Zr1.4Ta0.6O12 (LLZTO) pellet and Li metal by a conversion reaction of SnNx with Li metal at 300 °C. The LiySn alloy as a continuous and robust bridge between LLZTO and Li metal can effectively reduce the LLZTO/Li interfacial resistance from 4468.0 Ω to 164.8 Ω. Meanwhile, the Li3N as a fast Li‐ion channel can efficiently transfer Li ions and give their uniform distribution at the LLZTO/Li interface. Therefore, the Li/LLZTO@CCI/Li symmetric battery stably cycles for 1200 h without short circuit, and the all‐solid‐state high‐voltage Li/LLZTO@CCI/LiNi0.5Co0.2Mn0.3O2 battery achieves a specific capacity of 161.4 mAh g?1 at 0.25 C with a capacity retention rate of 92.6 % and coulombic efficiency of 100.0 % after 200 cycles at 25 °C. 相似文献

Four cone p-tert-butylcalix[4]arene-1,3-monothiacrown-5 ligands each with two N-(X)sulfonyl carbamoylmethoxy side arms are synthesized for comparison with analogs having only oxygen heteroatoms in the crown ether ring. Solvent extractions of hard alkali metal and alkaline earth metal cations, intermediate Pb2+, and soft Hg2+ from aqueous solutions into chloroform by these ligands are utilized to probe the effects of sulfur replacement in the crown ether ring on metal ion complexation. 相似文献

The first asymmetric total synthesis of (?)‐ligustiphenol is reported. The key step was conducted by exploiting a steric hindrance effect to control the formation of the adduct in a nucleophilic α‐Li‐phenolate addition reaction to the intermediate α‐oxo (?)‐menthyl ester. The synthesis is concise and feasible for the construction of analogous compounds and investigation of their biological activity. 相似文献

A supramolecular strategy for detecting specific proteins in complex media by using hyperpolarized 129Xe NMR is reported. A cucurbit[6]uril (CB[6])‐based molecular relay was programmed for three sequential equilibrium conditions by designing a two‐faced guest (TFG) that initially binds CB[6] and blocks the CB[6]–Xe interaction. The protein analyte recruits the TFG and frees CB[6] for Xe binding. TFGs containing CB[6]‐ and carbonic anhydrase II (CAII)‐binding domains were synthesized in one or two steps. X‐ray crystallography confirmed TFG binding to Zn2+ in the deep CAII active‐site cleft, which precludes simultaneous CB[6] binding. The molecular relay was reprogrammed to detect avidin by using a different TFG. Finally, Xe binding by CB[6] was detected in buffer and in E. coli cultures expressing CAII through ultrasensitive 129Xe NMR spectroscopy. 相似文献

Fullerenes, C60, modified with long alkyl chains form long-range ordered lamellar mesophases permitting a high C60 content. The mesomorphic fullerenes feature reversible electrochemistry and a comparably high electron carrier mobility making them attractive components for fullerene-based soft materials. 相似文献

Under the same experimental condition, changing the kinds of the transition metal (TM) of the reaction, we gained two new
compounds: Na3[Cu(Gly)2][Cr(OH)6Mo6O18]·13H2O 1, and NaCo2(gly)6ClO4
2. Compound 1 exhibits an unusual three-dimensional (3D) network constructed from [Cr(OH)6Mo6O18]3− building blocks, trinuclear Na+ ions and [Cu(gly)2] coordination complexes as linkers, representing the first example of a 3D extended framework based on Anderson type polyanions
and amino acid molecules. Compound 2 consists of an unusual 3D network grafted with Na[Co(gly)3]6 complexes. Moreover, compound 2 contains left-handed and right-handed helical chains.
