3-(2-Bromoacetyl)-6-fluoro-2H-chromen-2-one
The non-H atoms of the title compound, C(11)H(6)BrFO(3), are essentially coplanar (r.m.s. deviation for all non-H atoms = 0.074 Å). In the crystal, the molecules are linked by C-H⋯O and C-H⋯Br inter-actions.
متن کامل3-Acetyl-2-fluoro-6H-benzo[c]chromen-6-one
The title compound, C15H9FO3, was obtained in a one-pot synthesis by Suzuki-Miyaura cross-coupling and nucleophilic substitution reaction of 4'-chloro-2',5'-di-fluoro-aceto-phenone with o-(meth-oxy-carbon-yl)phenyl-boronic acid. The asymmetric unit contains two crystallographically independent mol-ecules related by a non-crystallographic inversion centre. There are face-to-face stacking inter-a...
متن کامل3-Benzyl-2H-chromen-2-one
The title compound, C(16)H(12)O(2), is a coumarin which was isolated from stones of the Chinese traditional medicine Clausena lansium. The pyrone ring is almost planar, with a mean deviation of 0.0135 (4) Å. The benzene ring (A) of the benzopyrone unit forms dihedral angles of 1.82 (5) and 72.86 (2)° with the pyrone ring and the substituent benzene ring, respectively. The crystal structure is s...
متن کامل3-[2-(Triphenylphosphanylidene)acetyl]-2H-chromen-2-one
In the title compound, C(29)H(21)O(3)P, a coumarin-substitued ylid, the P atom is linked to three benzene rings and a planar coumarin moiety via a methyl-enecarbonyl group. The bond lengths in the P=C-C=O fragment clearly indicate a delocalized system involving the olefinic and carbonyl bonds. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O inter-action that results in an S7 ...

In the title compound, C(19)H(11)N(3)O(2)SClBr, the chromene ring system and the thia-zole ring are each approximately planar, with maximum deviations of 0.033 (3) Å and 0.006 (3) Å, respectively. The mol-ecule adopts an E configuration about the central C=N double bond. The central thia-zole ring makes dihedral angles of 9.06 (14)° and 12.07 (11)° with the chloro-substituted phenyl ring and th...
