General description

Acetanilide is an aniline derivative. Crystal structure of acetanillide has been studied by X-ray diffraction. It crystallizes in orthorhombic system having space group of Pbca. Its photolysis has been studied in the presence of β-cyclodextrin (cycloheptaamylose). Aminoacetophenone derivatives are obtained by the Fries rearrangement of acetanilide in the presence zeolites Y and β.

Application

Acetanilide may be used in the synthesis of ortho-haloacetanilides via regioselective C-H functionalization/halogenation reaction in the presence of Pd(OAc)2 and Cu(OAc)2 catalyst. It may be used in the preparation of chlorosubstituted acetanilides.
