The kinetics of iodate formation is a critical factor in mitigation of the formation of potentially toxic and off flavor causing iodoorganic compounds during chlorination. This study demonstrates that the formation of bromine through the oxidation of bromi ...
Asym. substituted biaryldiphosphine ligands I (R1 = C1-6-alkyl or C3-10-cycloalkyl optionally substituted with one or more halogen atoms; R2 and R3 are equal and are C5-10-cycloalkyl or C1-6-alkyl, or R2 is C5-10-cycloalkyl or C1-6-alkyl, and R3 is aryl op ...
Provided is a process for prepn. of asym. substituted biaryldiphosphine ligands I (R1 = C1-6-alkyl, C3-10-cycloalkyl optionally substituted with one or more halogen atoms; R2, R3 = aryl, C5-10-cycloalkyl, C1-6-alkyl, or R2 = C5-10-cycloalkyl, C1-6-alkyl; R ...
A series of homologous bis-cyclometalated iridium(III) complexes Ir(2,4-di-X-phenyl-pyridine)2(picolinate) (X = H, F, Cl, Br) HIrPic, FIrPic, ClIrPic, and BrIrPic has been synthesized and characterized by NMR, X-ray crystallography, UV–vis absorption and e ...
The first part of this study consists in the investigation of the evaporation and the condensation rate of H2O in the presence of different types of ice in a low pressure flow reactor. The second part of the present work reports the study of chlorine activ ...
Numerous inorganic and organic micropollutants can undergo reactions with chlorine. However, for certain compounds, the expected chlorine reactivity is low and only small modifications in the parent compound's structure are expected under typical water tre ...
N,N-Dimethylsulfamide (DMS), a newly identified, ubiquitous degradation product of the fungicide tolylfluanide, has been shown to be a N-nitrosodimethylamine (NDMA) precursor during zonation. In this study, batch ozonation experiments in ultrapure buffered ...
The present invention concerns an intermediate of the following formula I in which R 1 and R 2 represent independently of each other a C 1 -C 12 alkyl group, a (C 1 -C 12 alkoxy)carbonyl group, optionally substituted by one, two or three halogen atom, a (C ...
The organometallic approach to the functionalization of arenes and heteroarenes has recently been investigated by our group introducing modifications of the standard methods. This includes, in particular, the basicity-driven heavy halogen migration, which ...
(2,6-Dichlorophenyl)trimethyl- and -triethylsilane exhibit untypical reactivity patterns toward strong bases. When treated at -100 DegC with lithium 2,2,6,6-tetramethylpiperidide, they give rise to two, with sec- or tert-butyllithium even three, different ...
