Abstract:C 13 H 13 N 5 O 6 ,monoclinic, P12 1 /c1(no. 14), a =14.501(2) Å, b =6.362(1) Å, c =17.166(2) Å, b =110.913(9)°,
Source of materialThe stock solutions was prepared by dissolving 0.5 mmol (Z)-1-(2,4-dinitrophenyl)-2-(3-methylcyclohex-2-enylidene)-hydrazine in 100 ml dry CH 2 Cl 2 .NOwas produced by the reaction of 1mol H2SO4 solution with saturated NaNO2 aqueous solution. The former was added to the latter, which was stirred under argon atmosphere. NO was carried by argon and purified by passing it through aser… Show more
“…The molecular structure of 2l in the solid state was confirmed by X-ray crystal structure analysis (Figure ) . Interestingly, the length of the newly formed C–N bond was only 1.341 Å, which was significantly shorter than a traditional C–N single bond but compared well to the bond length of a C–N double bond …”
An unprecedented approach to N-trifluoromethylations of electron-rich nucleophilic sites following a radical pathway is reported. Accordingly, various sulfoximines (19 examples) have been N-trifluoromethylated, providing previously unreported products with satisfying functionality tolerance in moderate to good yields. With a C-N bond length at the N-CF3 moiety of 1.341 Å the respective linkage is shorter than a traditional C-N single bond and comparable with that of a C-N double bond.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
