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-(Benzylsulfanyl)pyridine N-oxide
In the title compound, C(12)H(11)NOS, the dihedral angle between the oxopyridinium and phenyl rings is 58.40 (1)°. The crystal structure is stabilized by C-H⋯O hydrogen bonds, π-π stacking inter-actions involving the pyridinium rings [centroid-centroid distance = 3.6891 (9) Å] and C-H⋯π inter-actions.
متن کاملManganese(II) chloride complexes with pyridine N-oxide (PNO) derivatives and their solid-state structures
Three manganese(II) N-oxide complexes have been synthesized from the reaction of manganese(II) chloride with either pyridine N-oxide (PNO), 2-methyl-pyridine N-oxide (2MePNO) or 3-methyl-pyridine N-oxide (3MePNO). The compounds were synthesized from methano-lic solutions of MnCl2·4H2O and the respective N-oxide, and subsequently characterized structurally by single-crystal X-ray diffraction. Th...
متن کامل2-(2,3,5,6-Tetramethylbenzylsulfanyl)pyridine N-oxide
In the title compound, C(16)H(19)NOS, the durene ring and the oxopyridyl ring form a dihedral angle of 82.26 (7)°. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds, weak C-H⋯π inter-actions and π-π inter-actions [centroid-centroid distance of 3.4432 (19) Å], together with intra-molecular S⋯O [2.657 (2) Å] short contacts.
متن کامل2-(Mesitylmethylsulfanyl)pyridine N-oxide monohydrate
In the title compound, C(15)H(17)NOS·H(2)O, the benzene and pyridine rings form a dihedral angle of 71.18 (2)°. The intra-molecular S⋯O distance [2.737 (3) Å] is shorter than expected and, in terms of hybridization principles, the N-C-S angle [114.1 (2)°] is smaller than expected. The crystal structure is stabilized by inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonds. In addition, weak π-π s...
