Crystal structure of (E)-2-(tert-butylamino)-4-(tertbutylimino)naphthalen-1(4H)-one
(2018)
The title compound, C18H24N2O, is the first example of a naphthoquinone imine derivative isolated in the 4-imine/2-amine tautomeric form having bulky alkyl substituents at the N atoms. The molecular conformation is stabilized ...
1hJFH coupling in 2-fluorophenol revisited: Is intramolecular hydrogen bond responsible for this long-range coupling?
(John Wiley & Sons Ltd, 2011-11)
The present study shows that a hydrogen bond between the OH group and the fluorine atom is not involved in the 1hJFH spin-spin coupling transmission either for 4-bromo-2-fluorophenol or 2-fluorophenol. In fact, according ...

Crystal structure of 4-[(adamantan-1-yl)amino]naphthalene-1,2-dione
(2019)
The title compound, C20H21NO2, an example of a stable 1,2-naphthoquinone, was determined by single-crystal X-ray diffraction analysis at 100 K. This structure illustrates steric buttressing of the adamantanyl group, forcing ...
