The Front Cover shows a variety of dienophiles used in the synthesis of functionalized polycyclic aromatic hydrocarbons over the past decade via the Diels‐Alder reaction. Being discovered almost a century ago, this powerful synthetic method can be used for construction of new materials for organic electronics – one of the modern challenges of organic chemistry. Linear or angular, planar or curved, molecular or polymeric – the product scope is vast and will broaden even more with further development of new diene and dienophile components. More information can be found in the Minireview by P. A. Zaikin et al.
H, "C, and I5N NMR studies, including the use of the ''C NMR deuterium perturbation method, showed that the interaction between naphthalene or its methylated derivatives and the nitrosonium cation result in the formation of r-complexes. The chemical behaviour of these complexes was investigated; in particular, their ability to be converted into binaphthyl derivatives was established.
An effective protocol for the solvent‐free fluorination of electron‐rich aromatic compounds with 1‐chloromethyl‐4‐fluoro‐1,4‐diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (F‐TEDA‐BF4) is described. The protocol allows the easy and efficient isolation of fluorinated products in high yields and purities with low E factors (kgwaste kgproduct–1) by vacuum‐sublimation without the use of any solvent. The solid‐state fluorination of naphthalen‐2‐ol was studied by differential thermal analysis, and scanning electron microscopy was used to obtain evidence for the solid‐state process. The crucial influence of alkali‐metal carbonates on the rate of the solvent‐free fluorination of hydroxynaphthalenes and estrone was demonstrated.
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.
