“…For several years, there has been a great interest in the development of heterocyclic compounds in the chemical and pharmaceutical industry. [ 1–3 ] In this way, several oxacycle derivatives have prepared using different strategies; for example, the synthesis of an oxepan from an epoxide derivative and boron trifluoride etherate. [ 4 ] Besides, a study showed the preparation of some Δ 4 ‐disubstituted oxepen analogs via reaction of γ‐triphenylsilyl bishomoallylic with alcohol derivative in the presence of FeBr 3 .…”

There are several studies for the synthesis of oxacycle derivatives using some reagents which require special conditions have been reported. The aim of this study was to synthesize two oxocan derivatives from either imidazole or 2‐methylimidazole. The chemical structure was evaluated through both 1H NMR and 13C NMR spectroscopic analysis. The results showed a moderate yielding from oxocan derivatives. It should be mentioned that reagents used in this investigation are not expensive and do not require special conditions for handling.

“…Upon reacting [BiAr Mes ] 2 (3) with Jonas' complex at room temperature, the dark-violet solution of 3 in THF turned immediately to dark-brown (Figure 2). Monitoring of reaction progress by 1 H NMR spectroscopy revealed the selective formation of the η 2 -dibismuthene complex 4. However, despite prolonged stirring (overnight) or conducting the reaction under slight vacuum, complete conversion of 3 to 4 was never achieved.…”

“…1 H and 31 P{ 1 H} NMR as well as 13 C{ 1 H} NMR spectra were recorded in C 6 D 6 or THF-d 8 at 25 °C using a Bruker Avance I 300 MHz, Bruker Avance I 400 MHz, Bruker Avance III HD Ascend 500 MHz, and Bruker Avance III HD Ascend 700 MHz. 1 H NMR was reported as follows: chemical shift, multiplicity (s = singlet, d = doublet and t = triplet), coupling constant (J values) in Hz and integration. Chemical shifts (δ) were reported with respect to the corresponding solvent residual peak at 7.16 ppm for C 6 D 6 and 1.73 ppm for THF-d 8 .…”

The experimental realization of a variety of multimetallic systems composed by transition metals (TM) and heavier pnictogens has been widely explored via σ-bond activation of dipnictanes (Pn2R4), or even poly pnictanes (cyclo-(R n Pn) n , Pn = Sb and Bi and R = any substituent). In contrast, isolation of stable metallacyclic rings via TM-mediated activation of Sb and Bi multiple bonds are underexplored. Here, we reported the reactivity of “Sb = Sb” and “Bi = Bi” compounds with Jonas’ complex (CpCo(C2H4)2, Cp = C5H5) as the key electrophile to generate the “Co-Pn2” unit. Further exploiting of the synthetic potential of complex 2 using various reagents led to a series of stable multimetallic compounds (5, 6, and 7) containing low-valent heavy pnictogens. These findings have been supported by a thorough investigation of the electronic features of these multimetallic complexes.

“…By the virtue of the activity of the π-bonds, graphene can be easily manipulated chemically to endow it with various functionalities. 53,65,74 In 2015, Zhao et al first proposed a power generator through harvesting energy from moisture based on a GO film (GOF). 46 To fulfill the requirement of constructing the ion concentration gradient, the GOF was processed through MeA to build up a gradual content of oxygen-containing groups, where oxygen-containing groups are rich on one side and the other side has little of the groups (as shown in Figure 5a).…”

As an emerging candidate for a sustainable power supply, moisture-electric generators (MEGs) have attracted great attention in recent years. Unlike the conventional hydroelectric system, MEGs propose to harvest energy from ambient moisture, driven by either ion diffusion under a concentration gradient or the interaction between a solid–liquid interface governed by electrostatic theory. Two-dimensional (2D) nanomaterials, in particular hydrophilic graphene oxide (GO), have been considered as the most promising materials for high-performance MEGs owing to their unique structure and properties. In line with the development of 2D nanomaterials, the recent electrical output of a single MEG has been greatly raised from tens to hundreds of millivolts, which is capable of powering commercial electronics. Herein, we have reviewed the recent progress of 2D nanomaterials in MEGs. The mechanism of moisture-induced electricity generation and strategies for tailoring 2D nanomaterials to enhance the output performance of MEGs are discussed. The potential application of MEGs is also discussed in two categories: sensing and power supply. Finally, the existing challenges and the perspective of MEGs are proposed for future study.
