2-(4-Methylphenyl)-6-nitro-1,3-benzoxazole
The title compound, C14H10N2O3, is a π-conjugated mol-ecule containing a benzoxazole aromatic fused heterobicycle. The benzoxazole ring system is planar within 0.01 Å. The mol-ecule assumes an approximately flat conformation, the benzoxazole ring system forming dihedral angles of 6.52 (12) and 7.4 (3)° with the benzene ring and the nitro group, respectively. In the crystal, mol-ecules are conne...
متن کامل6-Nitro-1,3-benzothiazole-2(3H)-thione
In the title mol-ecule, C(7)H(4)N(2)O(2)S(2), the nitro group is twisted by 5.5 (1)° from the plane of the attached benzene ring. In the crystal, N-H⋯S hydrogen bonds link pairs of mol-ecules into inversion dimers, which are linked by weak C-H⋯O inter-actions into sheets parallel to (101). The crystal packing exhibits short inter-molecular S⋯O contacts of 3.054 (4) Å and π-π inter-actions of 3....
متن کامل6-Methylpyridine-2(1H)-thione
There are two unique mol-ecules in the asymmetric unit of the title pyridine-thione derivative, C(6)H(7)NS, each of which adopts the thione rather than the mercaptan form. The rings in both mol-ecules are essentially planar, with maximum deviations from the least-squares planes through all non-H atoms of 0.021 (2) and 0.017 (2) Å. In the crystal structure, the mol-ecules form centrosymmetric cy...
متن کامل3-[Chloro(phenyl)methyl]-6-methyl-1,2-benzoxazole
The title compound, C(15)H(12)ClNO, is a functionalized 1,2-benzoxazole with a chloro-(phen-yl)methyl substituent. The mol-ecule is V-shaped, the dihedral angle between the mean plane of the 1,2-benzoxazole system [maximum deviation = 0.023 (3) Å for the N atom] and the phenyl ring being 70.33 (14)°. There are no hydrogen-bonding inter-actions in the crystal structure, which is stabilized by va...
متن کاملSynthesis of benzoxazole-2-ones, benzothiazole-2-ones and their 2-thione derivatives: Efficient conversion of 2-thione to 2-oxo derivatives
A highly practical procedure for preparing benzoxazole-2-ones, benzothiazole-2-ones and its 2-thione derivatives using ethylchloroformate and carbon disulfide and the corresponding aminophenols and aminothiophenols as the starting materials in one-pot protocol is presented. The yields vary from good to excellent, the conditions are mild, and the use of toxic and harmful chemicals is avoided. An...
