The structure of the title compound, endo-(2R)-(-)-L-menthyl 1,4,5,6,7,7-hexachloro-4-norbornene-2-carboxylate, consists of discrete C18H22CL6O2 molecules related by a twofold screw axis. The relative configuration was determined and the chirality at the unknown centres was assigned on the basis of the known chiral centres of L-menthene. Both the average Csp(2)-Cl, 1.689(5), and Csp(3)-Cl, 1.753(3) Angstrom, distances are a little shorter than the literature values. The six-membered ring of the L-menthyl group has a chair conformation. C-O bond lengths in the carboxylate group are 1.194(7) and 1.323(7) Angstrom.

One dimensional nanobeam photonic crystal cavities are fabricated in an Er-doped amorphous silicon nitride layer. Photoluminescence from the cavities around 1.54 mu m is studied at cryogenic and room temperatures at different optical pump powers. The resonators demonstrate Purcell enhanced absorption and emission rates, also confirmed by time resolved measurements. Resonances exhibit linewidth narrowing with pump power, signifying absorption bleaching and the onset of stimulated emission in the material at ...
Synthesis of Bishomoinositols and an Entry for Construction of a Substituted 3-Oxabicyclo[3.3.1]nonane Skeleton

1,3,3a,7a-Tetrahydro-2-benzofuran was used as key compound for the synthesis of various bishomoinositol derivatives. The diene was subjected to an epoxidation reaction for further functionalization of the diene unit. The bisepoxide obtained was submitted to a ring-opening reaction with acid in the presence of water. Various bishomoinositols were synthesized. However, when the reaction was carried out in the presence of acetic anhydride, a substituted 3-oxabicyclo[3.3.1]nonane skeleton was formed. The mechan...
Interaction of TNT and Aluminum - A DFT Treatment
Türker, Burhan Lemi (2015-02-01)
Within the constraints of density functional theory [UB3LYP/6-31G(d,p) and UB3LYP/6-31++G(d,p)], TNT/Al and TNT/2Al composites are investigated, considering various multiplicity states. Depending on the localization of aluminum atoms in space and multiplicity of the composite systems, the structure of TNT undergoes various degrees of perturbations. It was shown that the presence of aluminum atoms affects the bond lengths, electron population as well as the HOMO-LUMO energy gap of TNT. All these are thought ...
Structural and electronic properties of AlP doped Huckel type cyclacene with four benzenoid rings
Erkoc, S; Malcıoğlu, Osman Barış (World Scientific Pub Co Pte Lt, 2003-11-01)
Cyclacene of the Huckel type having four benzenoid rings have been subjected to centric perturbations along both peripheral circuits such that Al and P atoms are alternatingly located. The present structure of perturbed cyclacene let two types of isomeric compounds to arise such that in one case the peri-positions and fusion-points occupied by Al and P atoms, respectively and in the other case reversal of occupation of locations occur. For these structures, AM1-RHF type semi-empirical calculations have been...
Synthesis of heterocyclic amine substituted novel 1,4-Aminoalcohols and applications in various asymmetric transformations
Keskin, Eda; Tanyeli, Cihangir; Department of Chemistry (2007)
Aminoalcohols are very important compounds used in various asymmetric transformations as chiral ligands or chiral auxiliaries. In this thesis, four novel heterocyclic amine substituted chiral 1,4-aminoalcohols were synthesized. In the synthetic strategy, amide esters were synthesized from (2S, 3R)-3-methoxycarbonylbicyclo[2.2.1]hept-5-ene-2-carboxylic acid by DCC coupling method. Subsequent reduction of these amide esters lead to target 1,4-aminoalcohols. The activities of these novel chiral 1,4-aminoalcoho...
