The article conveys some information:
The copper sulfide (sf-CuS) nano/micro particles without having organic surfactant mols. as the capping agent is synthesized. These particles with a flower-like architecture (micro flowers, mf) were obtained readily under the supersaturated condition at room temperature In these particles, the surface was freely available for adsorption and desorption reactions. When utilized as a catalyst in multicomponent cycloaddition reactions, the sf-CuS mf exhibited excellent catalytic activity compared with some other nanoparticles with surfactants. This sf-CuS mf catalyzed the one-pot synthesis of 1,2,3-triazole and β-hydroxy-1,2,3-triazole effectively from a variety of benzyl bromide derivatives and epoxides resp. Both these reactions proceeded in the presence of azide and phenylacetylene in the water at room temperature The catalyst was reusable, and there was no catalyst leaching observed during reactions. Synthesis of β-hydroxy triazoles and 1,2,3-triazoles under exceptionally mild conditions with high yields proved the sf-CuS mf as the robust and recyclable catalyst. In the experimental materials used by the author, we found 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Related Products of 622-95-7)
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) undergoes carbonylation in the presence of dimer of chloro(1,5-cyclooctadiene)rhodium(I) to yield the corresponding phenylacetic acid.Related Products of 622-95-7 It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
