摘要: Abstract The Ag@Carbon core-shell spheres were synthesized using a green, cheap, and easy process. products characterized by XRD, FESEM, TEM, MAP, EDX, Raman, FT-IR analysis. synthesis of novel class trichloro-1-nitroprop-1-en-2-amine via our as new Ag-catalyzed multicomponent reaction nitroalkane-trichloroacetonitrile adduct aryl halides in good yields under mild conditions is reported. catalytic activity was determined changing the solvent catalyst. effect investigated performing model presence catalyst various with DMF, DMSO, Toluene, THF, acetone acetonitrile solvents. Among them, found to be best terms time yield desired product. A comprehensive analysis Ag nanoparticles carbon references commercial AgI, AgBr, AgNO3, Ag2SO4 based catalysts has been performed.
