Applications of Cu(0) encapsulated nanocatalysts as superior catalytic systems in Cu-catalyzed organic transformations

Abstract

<p>In this review, the catalytic activity of encapsulated Cu-NPs in different important organic transformations is compared with those of a variety of organic, inorganic and hybrid porous materials bearing a traded metal ion.</p>

Catalytic Function of Cu (I) and Cu (II) in Total Synthesis of Alkaloids

“…[51] Total synthesis of (À )-indolactam V (31) was accomplished and reported by Tokuyam et al in 2015. [52] Total synthesis of (À )-indolactam V was started from 4-bromoindole (24), which reacted with MeMgBr to produce indolyl magnesium bromide (25). Then, aziridine 26 [53] was added to compound 25.…”

“…has been increasing field of investigation, in recent decades. [25] Until very recently, this was unquestionably not the case for Cu-catalyzed CÀ N, CÀ O, and CÀ C bond formation reactions, first discovered a while ago (1901) by Ullmann and Goldberg. [19a-c,26] These revolutionary contributions obviously opened a gateway for the development of Cu-catalyzed coupling reactions and in fact are the basis of today's developments.…”

Design of a new method for one-pot synthesis of 2-amino thiazoles using trichloroisocyanuric acid in the presence of a novel multi-functional and magnetically catalytic nanosystem: Ca/4-MePy-IL@ZY-Fe3O4

“…Zeolites as porous crystalline aluminosilicates have recently emerged as a signicant class of high-tech materials for immobilization catalysts due to their high surface area, nanoporous crystalline structure, high thermostability, persistence in all organic solvents, lack of waste or disposal issues, ability to conduct cation exchange and safety in addition to many other industrial and environmental benets. [22][23][24] Zeolite-NaY has been a source of signicant issues in uid catalytic cracking (FCC) and gasoline production because of its signicant acidity, great hydrothermal stability, and low price. Recent times have seen the usage of zeolite-NaY as the best support for heterogeneous catalysts.…”

Recent advances in metal-free heteroatom-doped carbon heterogonous catalysts

“…[53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68] Following, the same interest we have collected and reviewed the most recent activities on the applications of different organic transformations being performed effectively under heterogeneous catalysis. [69][70][71][72][73][74][75] In this review, we will mainly focus on the latest developments (2015 onwards) of heteroatom-doped carbon materials (single-element B-, N-, S-, and P-doped, dual-elements doped, and triple-elements doped carbons) as promising metal-free heterogeneous catalysts, including the catalysts preparation methods with an emphasis on their application in various organic transformations (oxidation, hydrogenation, hydrochlorination, dehydrogenation, coupling, etc. ).…”
