7-Methoxyindan-1-one
In the title compound, C(10)H(10)O(2), the 1-indanone unit is essentially planar (r.m.s. deviation = 0.028 Å). In the crystal, molecules are linked via C-H⋯O hydrogen bonds, forming layers lying parallel to the ab plane. This two-dimensional structure is stabilized by a weak C-H⋯π inter-action. A second weak C-H⋯π inter-action links the layers, forming a three-dimensional structure.
متن کامل7-Hydroxyindan-1-one
In the title compound, C(9)H(8)O(2), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The dihedral angle between the mean plane of the S(6) ring and the benzene ring is 1.89 (2)°. In the crystal, inversion-related mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming a cyclic dimers with R(2) (2)(12) graph-set motif. Weak inter-molecular C-H⋯O(carbon-yl) and C-H⋯O(hy-dro...
متن کامل7-Methoxy-3,4-dihydronaphthalen-1(2H)-one
In the title compound, C(11)H(12)O(2), the six-membered ketone ring fused to the 7-meth-oxy benzene ring adopts a slightly distorted envelope configuration with the central methyl-ene C atom being the flap. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions, which lead to supra-molecular layers in the bc plane.
متن کاملSELECTIVE CYCLIZATION OF 2-PROPARGYLTHIO-6-METHYL-PYRIMIDIN- 4(1 H)-ONE TO THIAZOLO [3,2-a] PYRIMIDIN 7-ONE
Selective transformation of 2-propargylthio-6-methyl-pyrimidin-4(1H)On e (2) to 3,5-dimethyl-7H-thiazolo [3,2-a] pyrimidin-7-one (3) is performed under the conditionof base catalysis . For elucidation of structure, palladium catalyzed cyclization reaction of (2) was carried out and the structures of the products were assigned (5) and (6). These compounds underwent isomerization to (3) and (4...
متن کامل7-Nitro-5H-1-benzothiopyrano[2,3-b]pyridin-5-one
In the mol-ecule of the title compound, C(12)H(6)N(2)O(3)S, the central heterocyclic ring is oriented at dihedral angles of 3.25 (6) and 2.28 (7)° with respect to the benzene and pyridine rings, respectively. The dihedral angle between the benzene and pyridine rings is 5.53 (7)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains.
