A direct pyridinium C-H sulfonylimination has been developed for the synthesis of sulfonyl iminopyridine derivatives I (R = H, CN, Ph, thiophen-2-yl, etc.; R1 = H, OMe, Ph, thiophen-3-yl, etc.; R2 = H, cyclopropyl, Ph, 4-bromophenyl, etc.; R1R2 = -CH=CH-CH=CH-; R3 = Me, Et, i-Pr, etc.; R4 = Et, Ph, pyridin-3-yl, etc.) with high efficiency. This transformation features the direct and efficient formation of a C=N bond with a high functional group tolerance under metal-free conditions. The spectroscopic properties potentially enable these sulfonyl iminopyridine compounds I to be useful new emitting materials. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6Quality Control of 3-(Trifluoromethyl)benzene-1-sulfonyl chloride).
3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6) 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).Quality Control of 3-(Trifluoromethyl)benzene-1-sulfonyl chloride
