[(1R,4S)-(+)-3-Benzoyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-olato-κ2 O 2,O 3](η4-norbornadiene)rhodium(I)
In the title complex mol-ecule, [Rh(C(17)H(19)O(2))(C(7)H(8))], the rhodium(I) metal centre is coordinated by the O atoms of a benzoyl-camphorate anion and the C=C bonds of the norbornadiene mol-ecule into a slightly distorted square-planar coordination geometry. The six-membered chelate ring is essentially planar (r.m.s. deviation = 0.0378 Å) and forms a dihedral angle of 31.67 (11)° with the phenyl ring.
rac-Ethyl (2Z)-3-{2-[(Z)-4-ethoxy-4-oxobut-2-en-2-ylamino]cyclohexylamino}but-2-enoate
The asymmetric unit of the title compound, C18H30N2O4, contains two independent molecules. In each molecule, the cyclohexane ring adopts a chair conformation with equatorial orientation of the substituents, and the conformation is stabilized by two intramolecular N—H...O hydrogen bonds, forming rings of S(6) graph-set motif. One ethoxy group and one ethyl group are disordered over two sets of sites with refined occupancy ratios of 0.704 (2):0.296 (2) and 0.505 (3):0.495 (3), respectively. In the crystal, a weak intermolecular C—H...O hydrogen interaction is observed, involving the O atom of the major component of the disordered eth…
(Z)-4-(2-Naphthylamino)pent-3-en-2-one
The title compound, C15H15NO, which was synthesized under solvent-free conditions by the reaction of acetoacetone and 2-naphthylamine, adopts a Z conformation about the C=C bond. The enamine–ketone fragment is approximately planar [maximum deviation = 0.026 (3) Å] and forms a dihedral angle of 39.78 (3)° with the naphthalene ring system. An intramolecular N—H...O hydrogen bond is observed.
(5R)-5-[(1R)-2,2-Dichloro-1-methylcyclopropyl]-2-methylcyclohex-2-en-1-one
The title compound, C(11)H(14)Cl(2)O, was synthesized by the reaction of a dichloro-methane solution of (R)-carvone and potassium tert-butano-late in the presence of a catalytic amount of benzyl-triethyl-ammonium chloride in chloro-form. The cyclo-hexene ring adopts a half-boat conformation. The cyclo-propyl ring is unsymmetrical, the shortest C-C bond being distal to the alkyl-substituted C atom. The crystal packing is stabilized only by van der Waals inter-actions.
(S)-4-(2-Chloropropan-2-yl)-1-(2,2,2-trichloroethyl)cyclohexene
The title compound, C(11)H(16)Cl(4), was synthesized by the reaction of (1S)-β-pinene with triethyl-amine in the presence of ZnCl(2). The cyclo-hexene ring assumes a half-boat conformation. The crystal packing is governed only by van der Waals inter-actions. The structure, which has been refined in P2(1), presents a striking P2(1)/m pseudosymmetry.
