“…Analysis of the potential functions of possible internal rotation of the functional groups in [3][4][5][6][7][8] shows that in all these cases, there is only one stable geometric configuration. The absence of the conformers in these cases can be explained by the presence of the common ring and substituent p-systems in the molecules of heterocyclic N-oxides.…”

“…[7] have concluded that the p-conjugation in the heteroaromatic ring increases in the series: 4-nitropyridine-N-oxide PyO) \ 4-chloropyridine-N-oxide (4-ClPyO) \ pyridine-N-oxide (PyO) \ 4-methylpyridine-N-oxide(4-MePyO). The crystal structure of PyO, 4-NO 2 PyO, and 4-MePyO has been investigated by X-ray crystallography [8,9].…”

“…[43] Bentmann and co-workers reported the crystal structure of pyridine N-oxide hydrogen-bonded to di-tert-butylfluorosilanol with a O-N pyridyl bond length 0.043 Å shorter than that of the coordinated OPy in complex 2 [1.316(3) vs. 1.359(5) Å]. [44] The thermolysis of complexes 1 and 2 in 1,2-[D 4 ]dichlorobenzene results in decomposition at 100°C with no evidence of phenol production. It is worth noting in the context of the "organometallic Baeyer-Villiger reaction" (OMBV) [41,45,46] for oxy-insertion into metal-hydrocarbyl bonds, which was delineated by Goddard, Periana, and coworkers, [37][38][39] that 1 and 2 are rare examples of isolated complexes that correspond to the Criegee intermediate of the classical BV mechanism (Scheme 2).…”

“…[2][3][4][5][6] Sowohl Silanole als auch Silandiole sind wertvolle Bausteine in der Synthesechemie und zeigen eine ausgeprägte Tendenz zur Bildung von Wasserstoffbrückennetzwerken. [7][8][9][10][11][12][13][14][15] Die Bildung von Koordinationsaddukten von Silanolen mit sauerstoff-und stickstoffhaltigen Basen, die sich leichter bilden als die entsprechenden Alkohol-Addukte, [8,11] und die Verwendung zur selektiven Wirt-Gast-Komplexierung von Alkoholen und Aminen unterstreichen dieses Verhalten. [9,12,16] Ebenso bilden die verwandten a,w-Siloxandiole, HO[SiR 2 O] n H, inter-und intramolekulare Wasserstoffbrücken, die häufig zur Bildung von Ringstrukturen führen (Schema 2).…”

[13][14][15] Im Falle des Monokaliumsilanolat-Salzes (Schema 2, rechts) ist bemerkenswert, dass die Wechselwirkung von Kalium-Kationen mit dem Silanolat sowie dem Silanol-Sauerstoff im Hinblick auf die Bildung einer intramolekularen Wasserstoffbrücke begünstigt wird, was dementsprechend zu einem Ring führt, der das Kalium-Ion enthält.…”
