inexpensive raw materials, showing its practical synthetic value in organic synthesis. A novel and convenient method for the synthesis of aryl thioamides from aryl aldehydes and tetramethylthiuram disulfide (TMTD) without the use of sulfurating reagent was explored. In the presence of CuI and di-tert-butyl peroxide (DTBP), various aryl thioamides were prepared with good to excellent yields, tetramethylthiuram
A solution of sulphur in boiling dimethylformamide is a convenient thiation agent. Activated hydrogen and halogen atoms are replaced by thiol groups and further reactions may then occur, often involving dimethylamine liberated from the solvent. However, since the amine is present only in low concentrations, products are sometimes isolated which are formed only in small quantity in the presence of an
AbstractNovel copper‐catalyzed three‐component reactions of phenylacetonitrile, sulfur and DMF (dimethyformamide) for the selective preparation of N,N‐dimethylthiobenzamide and N,N‐dimethyl‐2‐phenylethanethioamides in yields of up to 96% are described.magnified image
