[(2,3,5,6-?)-Bicyclo-[2.2.1]hepta-2,5-diene]dibromidopalladium(II).

ABSTRACT: In the title complex, [PdBr(2)(C(7)H(8))], the Pd(II) ion lies in a distorted square-planar environment defined by the two Br atoms and the mid-points of the two ?-coordinated double bonds of bicyclo-[2.2.1]hepta-2,5-diene. The complex is disposed about a crystallographic mirror plane parallel to the ac plane passing through the Pd, Br atoms and the centre of the diene ligand.

In the title complex, [PdBr(2)(C(7)H(8))], the Pd(II) ion lies in a distorted square-planar environment defined by the two Br atoms and the mid-points of the two π-coordinated double bonds of bicyclo-[2.2.1]hepta-2,5-diene. The complex is disposed about a crystallographic mirror plane parallel to the ac plane passing through the Pd, Br atoms and the centre of the diene ligand. ...[more]

Project description:The title compound, [Ni(C(5)H(5))(C(13)H(7)N(2))(C(18)H(15)P)] or (η(5)-C(5)H(5))(PPh(3))Ni-C C-C(7)H(6)-C(H)=C(CN)(2), contains an unusual disubstituted norbornadienyl (NBD) ligand containing ethynyl (-C C-) and dicyano-vinyl [-C(H)=C(CN)(2)] groups. Disorder is present in the NBD group with site occupancies of 0.636 (10) and 0.364 (10) for two distinct orientations. There are no strong hydrogen bonds and the primary inter-actions are weak C-H⋯π(arene) inter-actions.

(1S,4S)-2-(2,4-Difluoro-phen-yl)-5-[(4-methyl-phen-yl)sulfon-yl]-2,5-diaza-bicyclo-[2.2.1]hepta-ne.

Project description:In the title mol-ecule, C(18)H(18)F(2)N(2)O(2)S, the two benzene rings, which are oriented in opposite directions with respect to the rigid 2,5-diaza-bicyclo-[2.2.1]heptane core, form a dihedral angle of 17.2?(1)°. Weak inter-molecular C-H?O, C-H?F and C-H?N contacts consolidate the crystal packing.

Project description:Although the mol-ecular structure of the title compound, C22H32N4O8, displays a twofold symmetry of the mol-ecule including the meth-oxy and methyl substituents, no crystallographic twofold symmetry is observed in the X-ray structure analysis. The carbonyl O atoms alternately point to different sides of the plane defined by the carbonyl C atoms. Two meth-oxy groups are oriented inside the mol-ecules cavity. The H atoms of two methyl groups are disordered over two orientations and were refined using a split model.

Regioselective palladium-catalyzed ring-opening reactions of C1-substituted oxabicyclo[2,2,1]hepta-2,5-diene-2,3-dicarboxylates.

Project description:Palladium-catalyzed ring-opening reactions of C1 substituted 7-oxanorbornadiene derivatives with aryl iodides were investigated. The optimal conditions for this reaction were found to be PdCl2(PPh3)2, ZnCl2, Et3N and Zn in THF. Both steric and electronic factors played a role in the outcome of the reaction as increasing the steric bulk on the bridgehead carbon decreased the yield. These reactions were found to be highly regioselective, giving only one of the two possible regioisomers in all cases. A diverse collection of novel, highly substituted biphenyl derivatives were obtained.

5-Amino-3-eth-oxy-1,8,8-trimethyl-2-aza-bicyclo-[2.2.2]octa-2,5-diene-4,6-dicarbo-nitrile.

Project description:The title 2-aza-bicyclo-[2.2.2]octa-2,5-diene derivative, C(14)H(18)N(4)O, crystallized out with two independent mol-ecules with similar conformations in the asymmetric unit. In each mol-ecule, the three six-membered rings adopt boat conformations. The mol-ecules exist in the enamine form. In the crystal, mol-ecules are linked by N-H⋯O and N-H⋯N hydrogen bonds into a two-dimensional network parallel to the ab plane.

2,5-Dichloro-3,6-diisopropyl-cyclo-hexa-2,5-diene-1,4-dione.

Project description:The mol-ecule of the title compound, C(12)H(14)Cl(2)O(2), lies about an inversion center. The six-membered ring is almost planar, with the largest deviation from the least-squares plane being 0.014 (4) Å. The mol-ecular conformation is stabilized by a weak intra-molecular C-H⋯O hydrogen bond. In the crystal, mol-ecules are packed into stacks along the c-axis direction, with an inter-centroid separation of 4.811 (2) Å. Neighboring mol-ecules within the stack are related by the c-glide plane.
