“…Various copper(II) complex is used for selective oxidation of olefins homogeneous [29][30][31] and heterogeneously [32][33][34] using TBHP and H2O2 as oxidants. The copper based catalyst for the oxidation of alkynes has not been much explored to date [35][36][37][38][39] . Oxidation of alkynes using the Cu-catalyzed mechanism is highly efficient [40] .…”

Aldehyde, 1,2-diketones, and acid were prepared by copper-catalyzed oxidation of phenyl propyne, using t-BuOOH as the oxidant, heterogeneously. Aldehyde is formed as a major product under neutral conditions. Under mild conditions, catalysis was carried out using catalytic amounts of [Cu(L)Br] with N-methyl benzimidazolyl Schiff base ligand and stoichiometric amounts of oxidant in CH3CN. The several properties of the catalyst were characterized by using UV-Vis, FT-IR, PXRD, CV, and Electron paramagnetic resonance techniques. Comparative SEM measurement of catalyst before and after the catalysis shows that the morphology and size of rods affect the catalytic efficiency. The percentage yields of products were determined by GC-MS.
