General description

Pd(OAc)2 and Cu(OAc)2 catalyzed regioselective C-H functionalization/halogenation of acetanilide has been reported to afford ortho-haloacetanilides. Crystal structure of acetanilide has been studied by X-ray diffraction. Photorearrangement of acetanilide has been studied in the presence of β-cyclodextrin (cycloheptaamylose). Two-color REMPI (resonance enhanced multiphoton ionization) and ZEKE (zero kinetic energy photoelectron) spectra of the trans-acetanilide·H2O complex has been reported. Femtosecond IR spectroscopy of delocalized NH excitations of crystalline acetanilide has been studied. Fries rearrangement of acetanilide over zeolites Y and Beta affords corresponding aminoacetophenones.

Femtosecond IR spectroscopy of delocalized NH excitations of crystalline acetanilide confirms that self-trapping in hydrogen-bonded peptide units exists and does stabilize the excitation. Two phonons with frequencies of 48 and 76 cm (-1) are identified as the major degrees of
