“…Negative shifts of peaks corresponding to carboxyl groups from 1690 cm À1 to 1650 cm À1 were observedi nt he FTIR spectra of CNNS-BTEC-Cu-1, CNNS-BTEC-Cu-3, and CNNS-BTEC-Cu-5, whichr esulted from the coordination interaction betweenc opper(II) and carboxyl groups. [17] Similarr esults were also obtained by conducting XRD measurements (see the Supporting Information, Figure S1). With the increasing ratio of added BTEC, weak peaks ranging from 12.08 to 33.08 emerged in the XRD patterns of CNNS-BTEC-Cu-3 and CNNS-BTEC-Cu-5, which corresponded to the typical XRD pattern of BTEC ( Figure S2).…”

“…The intensity of peaks corresponding to carboxyl groups in CNNS‐BTEC‐Cu‐1, CNNS‐BETC‐Cu‐3, and CNNS‐BTEC‐Cu‐5 increased with the increasing ratio of BTEC in these samples. Negative shifts of peaks corresponding to carboxyl groups from 1690 cm −1 to 1650 cm −1 were observed in the FTIR spectra of CNNS‐BTEC‐Cu‐1, CNNS‐BTEC‐Cu‐3, and CNNS‐BTEC‐Cu‐5, which resulted from the coordination interaction between copper(II) and carboxyl groups . Similar results were also obtained by conducting XRD measurements (see the Supporting Information, Figure S1).…”

It is of great significance to fabricate a full‐spectrum‐active photocatalysts for more efficient utilization of solar energy. An improved metal‐to‐ligand charge transfer (MLCT) mechanism is proposed for a photocatalyst based on graphitic carbon nitride (g‐C3N4). UV/Vis spectroscopy indicates that the as‐prepared photocatalyst absorbs light at λ<1100 nm. The rather stable photocatalyst is found to be 26.1 times more active in photocatalytic hydrogen evolution (868.9 μmol h−1 g−1) than bulk g‐C3N4 (B‐CN) under visible light. The material exhibits high activity under near‐infrared (NIR) irradiation (49.1 μmol h−1 g−1). The mechanism of photocatalytic activity and stability are investigated by both experiment and theory. This proposed mechanism may have great potential for engineering renewable photocatalysts in the future.

“…The first step was similar to the previous one, 1,3-DCH reacted with two molecules of the corresponding pyrazole derivative. The final Cu(II) complex showed good catalytic properties in the oxidation of catechol [126]. Cooper (II) complexes were also obtained via the synthesis of a bipyrazolic ligand, bearing two carboxyl groups ( Figure 12).…”

Polynuclear metals have many potential applications, e.g., therapeutic agents (e.g., photocleavage of DNA), photovoltaic components, photocatalysts, magnetic materials and tuneable chemical sensors [127][128][129][130].…”

Preparation and Uses of Chlorinated Glycerol Derivatives

Crude glycerol (C3H8O3) is a major by-product of biodiesel production from vegetable oils and animal fats. The increased biodiesel production in the last two decades has forced glycerol production up and prices down. However, crude glycerol from biodiesel production is not of adequate purity for industrial uses, including food, cosmetics and pharmaceuticals. The purification process of crude glycerol to reach the quality standards required by industry is expensive and dificult. Novel uses for crude glycerol can reduce the price of biodiesel and make it an economical alternative to diesel. Moreover, novel uses may improve environmental impact, since crude glycerol disposal is expensive and dificult. Glycerol is a versatile molecule with many potential applications in fermentation processes and synthetic chemistry. It serves as a glucose substitute in microbial growth media and as a precursor in the synthesis of a number of commercial intermediates or fine chemicals. Chlorinated derivatives of glycerol are an important class of such chemicals. The main focus of this review is the conversion of glycerol to chlorinated derivatives, such as epichlorohydrin and chlorohydrins, and their further use in the synthesis of additional downstream products. Downstream products include non-cyclic compounds with allyl, nitrile, azide and other functional groups, as well as oxazolidinones and triazoles, which are cyclic compounds derived from ephichlorohydrin and chlorohydrins. The polymers and ionic liquids, which use glycerol as an initial building block, are highlighted, as well.

A series of triazole derivatives containing a pyrazole moiety were synthesized and characterized by 1H NMR, 13C NMR, and HRMS. The herbicidal activities of these compounds were tested against lettuce and bentgrass. Most of the tested compounds were moderately herbicidal activity against lettuce and bentgrass. Among them, compounds 6f and 6g had the highest herbicidal activity (80% inhibitory) against lettuce and bentgrass.
