A Technological Investigation on Refinement of high purity Cyclohexane Oxide
Fine Chemical Intermediates, 2001Co-Authors: Wang KaiAbstract:The high purity Cyclohexane Oxide was Cyclohexane Oxide from 80% Cyclohexane Oxide by the reation with boron trifluoride ethyl ether, hydramine to produce high boiling point material. The optimum conditions were obtained with 80% yield and 98% purity over, respectively.

Preparation and crystal structure of spiro(5,7-dimethoxy-1(1H)oxo-2-benzopyran-3(4H),1′-Cyclohexane)
Journal of Chemical Crystallography, 2005Co-Authors: V. K. Gupta, D. I. Brahmbhatt, U. R. Pandya, S. GoswamiAbstract:Spiro(5,7-dimethoxy-1(1H)oxo-2-benzopyran-3(4H),1′-Cyclohexane) (C_16H_20O_4) was prepared by alkylation of o -lithio 3,5-dimethoxy- N -methyl benzamide with methylene Cyclohexane Oxide followed by alkaline hydrolysis and its crystal structure was determined by X-ray crystallographic techniques. The compound crystallizes into monoclinic space group P 2_1/ c with unit cell parameters: a = 11.914(3) Å, b = 9.861(3) Å, c = 12.508(7) Å, β = 91.34(3)^∘, Z = 4. The structure has been solved by direct methods and refined to R = 0.039 for 1870 observed reflections. The heterocyclic ring adopts distorted sofa conformation while Cyclohexane ring assumes a highly symmetric chair conformation. The dihedral angle between the mean planes of isocoumarin nucleus and Cyclohexane ring is 105.51(5)^∘. Molecules are held together in the crystal by C=H ... O hydrogen bonds.
