Trichloroisocyanuric acid (TCCA) is mariculture commonly used drug

Our goup has already shown that trihaloisocyanuric acids are efficient reagents to perform the cohalogenation and halofluorination of unsaturated compounds, preparation of epoxides, and halogenation of aromatic and dicarbonyl compounds. In this work, it is communicated our results on a new green Hunsdiecker reaction of cinnamic acids using trichloro- and trichloroisocyanuric acid (TCCA)
In the case of the reaction with trichloroisocyanuric acid (TCCA), the chloronium ion seems to be preferred, as the partial charge formed can be release by a new bond from the lone electron pair of chlorine, then justifying the best correlation with σ parameter obtained. On the other hand, the best correlation with σ+ parameter in the reaction with TBCA indicates a more significant redistribution of the positive charge in the TS. However, the reaction parameter ρ is not high enough to support a sole formation of a benzylic carbocation.
Select mariculture commonly used drugs trichloroisocyanuric acid (TCCA), the reaction rate was measured at different light intensities. Select the optimum lighting conditions at different pH values, different temperature conditions by ion chromatography chloride ion concentration in the water each time period were measured to study the photochemical degradation of the water. Results: under different conditions of light intensity and, TCCA Chlorine ion dissociation rate change is more obvious, and the dissociation rate decreases with increasing wavelength. UV irradiation conditions, the acidic solution to inhibit dissociation alkaline solution to promote dissociation; temperature conducive to degradation of the drug.
