Palladium(II)-Catalyzed meta-C-H Olefination: Constructing Multisubstituted Arenes through Homo-Diolefination and Sequential Hetero-Diolefination was written by Bera, Milan;Maji, Arun;Sahoo, Santosh K.;Maiti, Debabrata. And the article was included in Angewandte Chemie, International Edition in 2015.COA of Formula: C7H5ClF2 This article mentions the following:
The palladium-catalyzed synthesis of divinylbenzenes, e.g., I, by meta-C-H olefination of sulfonate-based arenes was reported. Successful sequential olefinations in a position-selective manner provided a novel route for the synthesis of hetero-dialkenylated products, which are difficult to access using conventional methods. Addnl., 1,3,5-trialkenylated compounds can be generated upon successful removal of the directing group. In the experiment, the researchers used many compounds, for example, 2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4COA of Formula: C7H5ClF2).
2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).COA of Formula: C7H5ClF2
