Synthesis of mono- and di-arylated acenaphthylenes and programmed access to dibenzo[j,l]fluoranthenes via palladium-catalysed C-H bond functionalisation was written by Shi, Xinzhe;Roisnel, Thierry;Soule, Jean-Francois;Doucet, Henri. And the article was included in Organic Chemistry Frontiers in 2018.Category: chlorides-buliding-blocks This article mentions the following:
C1-arylation and C1,C2-diarylation of acenaphthylenes via palladium-catalyzed direct arylation using either aryl bromides or benzenesulfonyl chlorides as aryl sources were reported. With aryl bromides, the mono-arylation was very selective, whereas with benzenesulfonyl chlorides C1,C2-diarylated acenaphthylenes were obtained in good yields. The reaction tolerated a wide variety of substituents including bromo or iodo. Moreover, the Pd-catalyzed intramol. C-H bond reaction of bromo-substituted C1,C2-diarylated acenaphthylenes provided the corresponding dibenzo[j,l]fluoranthenes. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6Category: chlorides-buliding-blocks).
3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Category: chlorides-buliding-blocks
