چکیده
The synthesis and structural characterisation of [BPh(bipy)] and [BCl(bipy)] are described both of which contain a direduced bipy ligand (bipy = 2,2'-bipyridyl) and are analogues of the fluorenyl anion; DFT calculations highlight differences in the electronic structure of both species compared to the fluorenyl anion.

متن کاملSYNTHESIS OF AMINO DERIVATIVE OF INDENE AND FLUORENE FROM IMIMIUM SALT GENERATED IN ETHEREAL LITHIUM PERCHLORATE SOLUTION
A series of amino derivative of 1-indene and 9-fluorene have been synthesized from their corresponding iminium salt, generated in situ in the concentrated ethereal lithium perchlorate solution, and 1-indenyl or 9-fluorenyl anions. The yields of the reactions depend on the kind of anion. Addition of 1-indeny anion to the iminium salt gives the amino derivative of 1-indene, while addition of fluo...

متن کاملThe structural and density state calculation of B Nitrogen doped silicene nano flake
In this paper, we study the effect of single Boron/Nitrogen impurityatom on electronic properties of a silicene nano flake. Our calculations are basedon density functional theory by using Gaussian package. Here, one Si atom insilicene nano flake substitutes with a Boron/Nitrogen atom. The results show thatsubstitution of one Si atom with single Boron/Nitrogen atom increases distanceof impurity ...
متن کاملInvestigating the Effects of Molecular Oxygen Impurity on the Quadrupole Coupling Constants of Boron Nitride Nanotubes: Computational Studies
Density functional theory (DFT) calculations have been performed to investigating the effects of themolecular oxygen impurity on the quadrupole coupling constant (Qcc) parameters of armchair and zigzagboron nitride nanotubes (BNNTs). Optimization processes have been performed to relax the original andimpure structures of the investigated BNNTs. Afterwards, the Qcc parameters have been evaluated...
