A further study of acetylacetone nitrosation.
The nitrosation of acetylacetone (AcAc) has been revised in an aqueous acid medium of perchloric acid and buffers of mono-, di-, or tri-chloroacetic acid. The results show that in the presence of buffers, under conditions of [nit] ≪ [AcAc] (nit = sodium nitrite) the reaction cannot be studied by UV-Vis spectroscopy, contrary to the recently published paper by García-Rio et al. (J. Org. Chem., 2...
متن کاملStabilization and destabilization of zirconium propoxide precursors by acetylacetone.
The stabilizing and destabilizing mechanism in the action of acetylacetone on zirconium propoxide precursors is revealed; the nature of heteroleptic intermediates provides an explanation.
متن کاملPhotodissociation dynamics of acetylacetone: The OH product state distribution
Acetylacetone in the supersonic jet, which exists predominantly as an enolic form, is found to give rise to the OH fragment after the p – p* transition induced by the UV absorption. The nascent OH product state distributions are determined using a laser-induced fluorescence technique at the excitation wavelengths of 291 and 266 nm. The OH fragment is vibrationally cold, and its rotational state...
متن کاملCo-extraction of lanthanoid(III) with various metal ions in the chelate extraction system with acetylacetone.
The co-extraction phenomenon was found in a typical chelate extraction system, in which the extraction of lanthanoid ion (Ln3+) with acetylacetone (Hacac) was highly enhanced by various metal ions (M(n+)) such as Cu2+, Al3+, and Zr4+. This phenomenon was ascribed to the formation of the 1:1 adduct between Ln(acac)3 and the M(acac),, extracted into the organic phase. The co-extraction occurred m...
متن کاملPhotochemistry of acetylacetone isolated in parahydrogen matrices upon 266 nm irradiation.
The photochemistry of the chelated enol form of acetylacetone (AcAc) was investigated by UV excitation of the S(2) state at 266 nm in parahydrogen matrices, complemented by experiments in neon and normal hydrogen matrices. Infrared (IR) spectroscopy, combined with theoretical calculations, was used to identify the photoproducts. Isomerization towards various non-chelated forms (no intramolecula...
