چکیده

In the first part of this study, diaryl disulfides react with 2?phenylpropanal in the presence of morpholine and produce the corresponding sulfide products in high yields. In another part, disulfides are in situ generated in the reaction mixture from aryl halides/CuI/Cyanodithioformate and coupled with 2?phenylpropanal to access aryl alkyl sulfides. KCN/CS2 system was also used for one-pot preparation of 6-amino-5-arylthiouracil derivatives from aryl halides. In this stance, uracil derivatives having desirable yields were obtained as well. Furthermore, this catalytic system was successfully applied for the high-yielding preparation of ?-hydroxy sulfides from aryl halides and styrene . In the last part of this thesis, aerobic oxidation of aromatic aldehydes in the presence of potassium cyanide under solvent-free conditions proceeds to produce good yields of the corresponding ester products in the absence of oxidant and metal species.
