Oxidation of Benzoins with Pyridine N-oxide - SbC15 (1 : 1) Complexes+
When a mixture of a few benzoins and a pyridine N-oxide SbC15 (1 : 1) complex (Complex A) was boiled in nitromethane, the corresponding benzils were obtained in various yields dependent upon the kinds of substituents in each reactant. The yield of benzil becames higher by adding some tertiary amines. In this reaction, tribenzylamine is a good accelerator to promote it. When Complex A, 4-picolin...
متن کامل2-(Mesitylmethylsulfanyl)pyridine N-oxide–18-crown-6 (2/1)
In the title compound, 2C(15)H(17)NOS·C(12)H(24)O(6), the asymmetric unit consists of one N-oxide derivative and one-half of the 18-crown-6 ether, which lies on an inversion centre. In the crown ether, the O-C-C-O torsion angles indicate a gauche conformation of the ethyl-eneoxy units, while the C-O-C-C torsion angles indicate planarity of these segments. In the N-oxide unit, the dihedral angle...
متن کامل4-[5-(4-Pyridyl)-1,3,4-oxadiazol-2-yl]pyridine N-oxide–isophthalic acid (1/1)
The title compound, C(12)H(8)N(4)O(2)·C(8)H(6)O(4), was synthesized from 4-[5-(4-pyrid-yl)-1,3,4-oxadiazol-2-yl]pyridine N-oxide and isophthalic acid. The two mol-ecules are linked through O-H⋯O and O-H⋯N hydrogen bonds. Weak intra-molecular π-π inter-actions between the two hydrogen-bonded chains result in the formation a one-dimensional supra-molecular curved tape (the face-to-face distance b...
متن کاملcatena-Poly[[aquasodium(I)]-μ-[2,2′-(disulfanediyl)bis(pyridine N-oxide)]-μ-(pyridine-2-thiolato 1-oxide)]
There are two monomeric units in the asymmetric unit of the polymeric title compound, [Na(C(5)H(4)NOS)(C(10)H(8)N(2)O(2)S(2))(H(2)O)](n). The Na(I) ions are six coordinated by four O atoms, one S atom and one water mol-ecule, forming a slightly distorted octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond stabilizes the conformation of the mol-ecule. The crystal packing is consolidated...
متن کاملtrans-Tetrakis[N-(adamantan-1-yl)pyridine-4-carboxamide]dichloridomanganese(II)–N-(adamantan-1-yl)pyridine-4-carboxamide (1/2)
The asymmetric unit of the title compound, [MnCl(2)(C(16)H(20)N(2)O)(4)]·2C(16)H(20)N(2)O, is composed of two coordinating N-(adamantan-1-yl)pyridine-4-carboxamide mol-ecules, one Cl(-) anion, an Mn(II) ion, lying on an inversion centre, and one free N-(adamantan-1-yl)pyridine-4-carboxamide mol-ecule. The distorted octa-hedral Mn environment comprises two terminal Cl atoms and four monodentate ...
