5,8-Dibromo-15,18-dimeth-oxy-2,11-dithia-[3.3]paracyclo-phane.

ABSTRACT: IN THE TITLE COMPOUND [SYSTEMATIC NAME: 1(2),1(5)-dibromo-5(2),5(5)-dimethoxy-2,7-dithia-1,5(1,4)-dibenzenaoctaphane], C(18)H(18)Br(2)O(2)S(2), the dihedral angle between the aromatic rings is 0.6?(2)° and their centroid separation is 3.251?(2)?Å, indicating that a trans-annular ?-? interaction occurs. The dimeth-oxy and dibromo substituents are located at crossed positions because of the electronic and the steric nature of the substituents.

2,11-Dibromo-5,8-dibut-yl[4]helicene.

Project description:A racemic mixture of the title compound, C(26)H(26)Br(2), a brominated [4]helicene, crystallizes, forming columns of stacked mol-ecules. There are two crystallographically unique mol-ecules in the asymmetric unit, both with the same helical handedness. As is typical with helicene congeners, the unique mol-ecules show short inter-atomic contacts between H atoms at the fjord region, with H?H distances of 1.87 and 1.94?Å. Mol-ecules with the same helical handedness segregate in the crystal packing, forming homochiral columns. The stacked mol-ecules are piled in a column with alternate orientations. The shortest C?C distance in the stacked mol-ecules is 3.306?(4)?Å.

4,12-Bis(2,2-dibromo-vinyl)[2.2]paracyclo-phane.

Project description:In the title compound, C(20)H(16)Br(4), both vinylic substituents were introduced by a Corey-Fuchs reaction using 4,12-diform-yl[2.2]paracyclo-phane as starting material. The title compound may be used as a valuable precursor for the synthesis of diethyn-yl[2.2]paracyclo-phane. The title mol-ecule is centrosymmetric with a crystallographic center of inversion between the centers of the two phenyl rings. A strong tilting is observed with an inter-planar angle between the best aromatic plane and the vinyl plane of 49.4?(5)°. No significant inter-molecular inter-actions are found in the crystal.
