3-Mesityl-2-oxo-1-oxaspiro­[4.4]non-3-en-4-yl benzoate

In the title compound, C(24)H(24)O(4), a derivative of the potent insecticide and miticide spiro-mesifen, one cyclo-pentane C atom is disordered over two positions with occupancies of 0.574 (12) and 0.426 (12), resulting in respective envelope and twisted conformations for the cyclo-pentane ring. The atom at the flap position is 0.620 (5) Å out of the mean plane formed by the other four atoms o...

3-Mesityl-2-oxo-1-oxaspiro­[4.4]non-3-en-4-yl 4-chloro­benzoate

The title compound, C(24)H(23)ClO(4), is a potent insecticide and miticide. The five-membered cyclo-pentane ring displays an envelope conformation with the atom at the flap position 0.611 (2) Å out of the mean plane formed by the other four atoms. The furan ring makes dihedral angles of 71.3 (2) and 81.9 (2)°, respectively, with the 2,4,6-trimethyl-phenyl and 4-chloro-phenyl rings. The dihedral...

In the title compound, C(28)H(31)ClO(4), the five-membered cyclo-pentyl ring displays an envelope conformation with the atom at the flap position 0.519 (3) Å out of the mean plane formed by the other four atoms. The furan ring makes dihedral angles of 72.9 (1) and 82.4 (1)°, respectively, with the trimethyl- and chloro-phenyl rings. The dihedral angle between the two benzene rings is 15.3 (1)°....

3-tert-Butyl-2-oxo-1-oxaspiro­[4.5]dec-3-en-4-yl 4-chloro­benzoate

The title tetronic acid derivative, C(20)H(23)ClO(4), which is a spiro-diclofen analogue, has two crystallographically independent mol-ecules in the asymmetric unit (Z' = 2). The cyclo-hexane rings in the respective mol-ecules A and B adopt chair conformations [four C atoms are planar with mean deviations of 0.013 (2) and 0.001 (2) Å, and the flap positions deviate by 0.653 (4) and -0.663 (3) Å...

In the title spiro-diclofen derivative, C(22)H(17)Cl(3)O(4), the cyclo-hexane ring adopts a chair conformation [four C atoms are planar with a mean deviation of 0.018 Å and the two C atoms at the flap positions deviate by 0.613 (4) and -0.668 (5) Å from the plane]. The dihedral angles between the furan ring and the two benzene rings are 55.78 (3) and 49.92 (3)°. Weak inter-molecular C-H⋯Cl inte...
