4-Fluoro-2-[(3-methylphenyl)iminomethyl]phenol
The title compound, C(14)H(12)FNO, crystallizes as the trans phenol-imine tautomer. The two benzene rings are essentially coplanar, being inclined to one another by 9.28 (7)°. This is at least in part due to the intra-molecular O-H⋯N hydrogen bond between the hy-droxy O atom and the imine N atom. The crystal structure is stabilized by an array of weak C-H⋯O and C-H⋯F inter-actions, which link t...

In the title compound, C(14)H(12)ClNO, the dihedral angle between the aromatic rings is 39.84 (7)°. In th crystal, mol-ecules are connected by O-H⋯N hydrogen bonds into chains parallel to [001]. In addition, a C-H⋯π contact occurs.
متن کامل2-Ethoxy-4-[2-(3-nitrophenyl)hydrazonomethyl]phenol
The title Schiff base compound, C(15)H(15)N(3)O(4), was prepared from a condensation reaction of 3-eth-oxy-4-hydroxy-benz-aldehyde and 3-nitro-phenyl-hydrazine. The mol-ecule is nearly planar; the dihedral angle between the hydroxy-benzene ring and the nitro-benzene ring is 6.57 (7)°. O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonding helps to stabilize the crystal structure.
متن کامل(6R)-2-tert-Butyl-6-[(4R,5S)-3-isopropyl-4-methyl-5-phenyloxazolidin-2-yl]phenol
In the title compound, C(23)H(31)NO(2), the lone pair on the nitro-gen atom is oriented to facilitate intra-molecular hydrogen bonding with the hydr-oxy group residing on the phenyl substituent. The five-membered ring adopts an envelope confornmation with the O atom at the flap. The absolute stereochemistry was verified by measurement of optical activity using a digital polarimeter.
متن کاملTrimethyl 5-(2-chloro-4-fluorophenyl)-2-phenylpyrrolidine-2,3,4-tricarboxylate
The title compound, C(22)H(21)ClFNO(6), was synthesized by the 1,3-dipolar cyclo-addition reaction of dimethyl maleate, methyl 2-amino-2-phenyl-acetate and 2-chloro-4-fluoro-benzaldehyde. The pyrrolidine ring possesses an envelope conformation and the two benzene rings are oriented at a dihedral angle of 68.28 (7)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure...
