Witryna14 kwi 2024 · Radical cyclizations of organohalides across olefins are highly useful transformations to access diverse cyclic skeletons. 15 Typically, the reductive cyclization of organohalides operating through a radical mechanism requires stoichiometric amounts of toxic organostannanes 16 and radical initiators such as AIBN 17 or Et 3 … Witryna21 mar 2024 · Organohalide-respiring bacteria can utilize several sets of functional enzymes to couple halogen removal with electron transfer from H2 or organic matter (e.g., formate and lactate) to organohalides for cell growth (Fincker and Spormann, 2024; Atashgahi et al., 2024). Consequently, microbial reductive dehalogenation …
WitrynaWe investigated concentrations of organohalides in Alert during a 3 week sampling campaign in spring 2006. In order to investigate the occurrence of species in the atmosphere and the snow pack, we have collected airsamples in electropolished canisters and snow samples by grab sampling including several depth profiles.
