“…12b) [114], refluxing in concentrated strong acids or bases [115,116], solution-phase oxygen radical reaction [117], using urea with a ball milling process, using molten hydroxides [118], or direct hydrothermal reaction with hydrogen peroxide. The hydroxylated h-BN sheets can be diversely derivatized using a silylation reaction with various silane compounds [119,120]. Despite those efforts, the membrane applications of h-BN sheets were restricted owing to their low exfoliation and production yield.…”

Membranes could reform the field of molecular separations by enabling new low energy manufacturing technologies. This review article discusses the current state of the art and the potential in the 2D-enabled membrane separation processes by highlighting emerging and existing areas in which robust 2D materials significantly impact the energy-efficient separation process. Analysis of 2D-enabled membrane classes and prospective materials for 2D-enabled membranes are also discussed with emphasis on the surface chemistry of basal plane engineered 2D materials.

“…h-BN nanosheets used with βCD and Pd(OAc) 2 found to be efficient in Heck couplings (see Scheme 22) [134] were also shown to be equally effective in triazole synthesis in combination with γCD and Cu(OAc) 2 [catalyst 1.7 % Cu(OAc) 2 :61-γCD-h-BN]. [174] The presence of Cu 2 + ions was shown by XPS binding energies of 934.1 eV (Cu 2p 3/2 ) and 954.0 eV (Cu 2p 1/2 ). In this case, alkynes were reacted with arylboronic acids in a two-step protocol in one pot.…”

Cyclodextrins are green, environmentally benign products available through the enzymatic degradation of starch for a multitude of varied applications. This review attempts to collect useful information with respect to catalytic studies performed with the use of cyclodextrin and modified cyclodextrin preparations applied in combination of or loaded with varied catalytically active species including metal ions, complexes, and metal particles. Major sections are about their use in hydrogenation, reduction, oxidation, hydroformylation and coupling reactions. Additional sections include their utilization in ring formation and ring opening as well as degradation of pollutants. In the last part, examples about ester hydrolysis, hydroboration and hydrosilylation, as well as hydrogen production are treated. Data collected and analyzed indicate the importance and high potential of cyclodextrin-based catalysts in sustainable chemistry.

“…However, recent publications have described the use of Cu(II) complexes as catalysts without the use of reducing agents. [113][114][115][116][117][118][119][120] Bagherzadeh et al 121 reported in 2019 the preparation of two Cu(II) complexes (Figure 6) and studied their catalytic potentials against the CuAAC reaction in the absence of reducing agents. The authors were able to prepare different 1H-1,2,3-triazole derivatives from a multicomponent reaction between benzyl chloride, sodium azide and different terminal alkynes with good yields.…”

The applications of the 1H-1,2,3-triazole derivatives are particularly attractive and have received prominent attention in scientific research. The characteristics of these heterocycles motivated the development of different strategies for their preparation and molecular diversification. Most of the synthetic procedures available in the literature are based on catalysis with copper salts. Therefore, this review has as complementary central focus and updates the information about the properties and the main methods for the preparation of 1H-1,2,3-triazole derivatives, with emphasis on methods involving 1,3-dipolar cycloaddition between organic azides and terminal alkynes catalyzed by copper.
