The photochemical reactivity of acyl azolium salts derived from aliphatic carboxylic acids has been investigated. These species, which serve as models for intermediates generated in N-heterocyclic carbene (NHC) organocatalysis, undergo Norrish type II elimination reactions under irradiation with UVA light analogy to structurally related aromatic ketones. Moreover, efficient Norrish-Yang cycliza...
1Department of Ecology, International Center for Science, High Technology & Environmental Sciences, Kerman, Iran *Corresponding author: [email protected] Abstract: Regarding to excess entry of heavy metals to the natural resources and the importance of heavy metals removal from the environment, in this investigation, the effect of some organic acid treatment on cadmium and lead abs...
Decomposition and corresponding mechanism of alachlor, an endocrine disruptor in water by ozonation were investigated. Results showed that alachlor could not be completely mineralized by ozone alone. Many intermediates and final products were formed during the process, including aromatic compounds, aliphatic carboxylic acids, and inorganic ions. In evoluting these products, some of them with we...
A practical, efficient, and operationally simple strategy for the ipsoiododecarboxylation and di-iodination of aromatic carboxylic acids using the low-cost commercial reagent succinimide (NIS) as iodine source is reported. This iodination or di-iodination process can be easily controlled through reaction conditions, thereby providing corresponding iodination or di-iodination products with high ...
