Convenient,Cost‐Effective,and Mild Method for the N‐Acetylation of Anilines and Secondary Amines

Abstract

An efficient, cost‐effective, and mild method for the N‐acetylation of anilines and secondary amines with ammonium acetate in acetic acid media at reflux temperature in good yield is described.     

Microwave‐Assisted Solid‐State Synthesis and Characterization of Thiohydantoin Derivatives

Abstract

A new and efficient solid‐state method for the preparation of thiohydantoins is reported. With this method, twelve thiohydantoin compounds have been synthesized in good to excellent yields (81–92%). In addition, this method has the advantages of high yields, a cleaner reaction, simple methodology, and short reaction times.     

Regioselective Hydroperoxygenation of Aralkanes and α,β‐Unsaturated Carbonyl Compounds Catalyzed by N‐Hydroxyphthalimide and 2,2′‐Azobis(4‐methoxy‐2,4‐dimethylvaleronitrile)

Abstract

Aerobic oxidation of aralkanes and α,β‐unsaturated carbonyl compounds in the presence of a catalytic amount of N‐hydroxyphthalimide (NHPI) and 2,2′‐Azobis(4‐methoxy‐2,4‐dimethylvaleronitrile) (V‐70) under 1 atmos. of oxygen at 30°C gave α‐hydroperoxyaralkanes and γ‐hydroperoxy‐α,β‐unsaturated carbonyl compounds, respectively.
