The oxidation of organic compounds by sulfonated porous carbon and H2O2 was studied at room temperature. Alkyl and aryl sulfides were oxidized to the corresponding sulfoxides or sulfones in excellent yields. Secondary alcohols were also converted to the corresponding esters/lactones and aldehydes to methyl esters in good yields. Moreover,aliphatic tertiary amines and substituted pyridines were oxidized to N-oxides.

This study obtains a suitable reaction to produce 86Y. The 86Y excitation functions via 86Sr(p,n)86Y, 86Sr(d,2n)86Y, 85Rb(3He,2n)86Y and 85Rb(α,3n)86Y reactions were calculated by TALYS-1.0 code and compared with the reported measurement. Requisite thickness of targets was obtained by SRIM code for each reaction. The 86Y production yield was evaluated with attention to excitation function and stopping power. The 86Sr(p,n)86Y reaction was determined as most interesting one due to its highest production yield and advantages to get high radionuclide and radiochemical purity.
