Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Ciunik, Z, once mentioned the application of 611-64-3, Name is 9-Methylacridine, molecular formula is C14H11N, molecular weight is 193.2438, MDL number is MFCD00143523, category is pyrrolines. Now introduce a scientific discovery about this category, Name: 9-Methylacridine.
Relationship between electron difference density distribution, planarity of the >N-O groups and intermolecular hydrogen bond systems in crystals of stable nitroxide radicals
The electron density distribution calculated for 2,2,6,6-tetramethyl-1-piperidinyloxy (1), 4-hydroxy-2,2,6,6-tetramethyl-1-piperidinyloxy (2) and 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy (3) free radicals on the basis of low-temperature X-ray single crystal diffraction experiments revealed some differences in region of the > N-O,groups. Generally, the experimental bonding density along the axis of the N-O bond is relatively low and asymmetric in cases of the pyramidal geometry of the aminoxyl group (1 and 2) and almost symmetrical for the planar geometry (3). The shape and distribution of electron densities in the region of the oxygen lone-pairs suggest that this atom is sp(3) hybridized but the spatial orientation of these maxima depends on hydrogen bond interactions (> N-O … H) in studied crystals. Also the relation between the direction of the relatively strong hydrogen bonds (O … H < 2.2 Angstrom) and the geometry of aminoxyl groups analysed for crystal structures collected in the Cambridge Structural Database showed that these interactions can affect the aminoxyl group geometry.
