Potassium superoxide stoechiometrically reacts with arylamidoximes with the selective formation of the corresponding benzamide and nitrogen oxides (mainly NO2-) in high yield.A similar oxidative cleavage of the C=NOH bond of N-hydroxy-arylguanidines also occurs upon reaction with KO2; the yield of the corresponding urea is lower and large amounts of the corresponding cyanamide are also formed.The significance of this reaction of O2.- with compounds containing a C=NOH bond in the biological formation of nitrogen oxides including NO is discussed.

The formation of aryl-alkyl ether bonds through cross coupling of alcohols with aryl halides represents a useful strategic departure from classical SN2 methods. Numerous tactics relying on Pd-, Cu-, and Ni-based catalytic systems have emerged over the past several years. Herein we disclose a Ni-catalyzed electrochemically driven protocol to achieve this useful transformation with a broad substrate scope in an operationally simple way. This electrochemical method does not require strong base, exogenous expensive transition metal catalysts (e.g., Ir, Ru), and can easily be scaled up in either a batch or flow setting. Interestingly, e-etherification exhibits an enhanced substrate scope over the mechanistically related photochemical variant as it tolerates tertiary amine functional groups in the alcohol nucleophile.

A new series of 2,4,5-trisubstituted oxazole were synthesized with good yields using simple methodology. All the compounds were thoroughly characterized by IR, NMR (1H and 13C) and mass spectrometry and structures of 2-(4-butyloxyphenyl)-4,5-dimethyloxazole (5b) and 4,5-dimethyl-2-(4-(octyloxy)phenyl)oxazole(5e) were unambiguously determined by X-ray crystallography. Evidently, the crystal structures of these compounds showed C-HaN and C-HaO intermolecular interactions. The electronic structures of these compounds were also studied by DFT at B3LYP/6-311G ++ level of theory.
Liquid Crystalline Primary Benzamides
Beginn, U.,Lattermann, G.
, p. 215 - 220 (2007/10/02)
Several alkoxybenzamides are synthesized and characterized by spectroscopic and chromatographic methods. 3,4,5-Tris(alkoxy)benzamides have been found to exhibit a mesophase of a columnar or stack-like type. - Keywords: liquid crystals, columnar phases, 3,
