Description

Description générale

Acetophenone (Methyl phenyl ketone) is an alkyl phenyl ketone. Its triplet absorption spectra in non-polar solvents has been evaluated by nanosecond laser photolysis. Photoreduction of acetophenone has been investigated. N-chelate ligands based on chiral oxazolines catalyzed enantioselective hydrosilylation of acetophenone with α-naphtylphenylsilane has been reported. Intersystem crossing of aromatic aldehydes and ketones (benzaldehyde, acetophenone and benzophenone) has been studied. Rhodium(I) complexes containing optically active 2-(2′-pyridyl)pyridines efficiently catalyzes the reduction of acetophenone.
