A Challenge to Chemical Intuition: Donor–Acceptor Interactions in H3BL and H2B+L (L=CO; EC5H5, E=N–Bi)
Authors: Erhardt Stefan , Frenking Gernot 
Published: April 2006

AbstractThe equilibrium geometries and bond energies of the complexes H3BL and H2B+L (L=CO; EC5H5: E=N, P, As, Sb, Bi) have been calculated at the BP86/TZ2P level of theory. The nature of the donor–acceptor bonds was investigated by energy decomposition analysis (EDA). The bond strengths of H3BL have the order CO>N>P>As>Sb>Bi. The calculated values are between De=37.1 kcal mol−1 for H3BCO and De=6.9 kcal mol−1 for H3BBiC5H5. The bond dissociation energies of the cations H2B+CO and H2B+EC5H5 are larger than for H3BL, particularly for complexes of the heterobenzene ligands. The calculated values are between De=51.9 kcal mol−1 for H2B+CO and De=122.1 kcal mol−1 for H2B+NC5H5. The trend of the BDE of H2B+CO and H2B+EC5H5 is N>P>As>Sb>Bi>CO. A surprising result is found for H2B+CO, which has a significantly stronger and yet substantially longer bond than H3BCO. The reason for the longer but stronger bond in H2B+CO compared with that in H3BCO comes mainly from the change in electrostatic attraction and π bonding at shorter distances, which increases more in the neutral system than in the cation, and to a lesser extent from the deformation energy of the fragments. The H2B+←NC5H5 π⊥ donation plays an important role for the stronger interactions at shorter distances compared with those in H3BNC5H5. The attractive interaction in H2B+CO further increases at bond lengths that are shorter than the equilibrium value, but this is compensated by the energy which is necessary to deform BH2+ from its linear equilibrium geometry to the bent form in the complex. The EDA shows that the contributions of the orbital interactions to the donor–acceptor bonds are always larger than the classical electrostatic contributions, but the latter term plays an important role for the trend in bond strength. The largest contributions to the orbital interactions come from the σ orbitals. The EDA calculations suggest that heterobenzene ligands may become moderately strong π donors in complexes with strong Lewis acids, while CO is only a weak π donor. The much stronger interaction energies in H2B+EC5H5 compared with those in H3BEC5H5 are caused by the significantly larger contribution of the π⊥ orbitals in H2B+EC5H5 and by the increase of the binding interactions of the σ+π∥ orbitals.

AbstractTwenty‐eight novel salts with tetramethyl‐, tetraethyl‐, and tetrabutylammonium and 1‐butyl‐3‐methylimidazolium cations paired with 3,5‐dinitro‐1,2,4‐triazolate, 4‐nitro‐1,2,3‐triazolate, 2,4‐dinitroimidazolate, 4,5‐dinitroimidazolate, 4,5‐dicyanoimidazolate, 4‐nitroimidazolate, and tetrazolate anions have been prepared and characterized by using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and single‐crystal X‐ray crystallography. The effects of cation and anion type and structure on the physicochemical properties of the resulting salts, including several ionic liquids, have been examined and discussed. Ionic liquids (defined as having m.p.<100 °C) were obtained with all combinations of the 1‐butyl‐3‐methylimidazolium cation ([C4mim]+) and the heterocyclic azolate anions studied, and with several combinations of tetraethyl or tetrabutylammonium cations and the azolate anions. The [C4mim]+ azolates were liquid at room temperature exhibiting large liquid ranges and forming glasses on cooling with glass‐transition temperatures in the range of −53 to −82 °C (except for the 3,5‐dinitro‐1,2,4‐triazolate salt with m.p. 33 °C). Six crystal structures of the corresponding tetraalkylammonium salts were determined and the effects of changes to the cations and anions on the packing of the structure have been investigated.
Quantification of Ultrasound‐Induced Chain Scission in PdII–Phosphine Coordination Polymers
Authors: Paulusse Jos M. J. , Huijbers Jeroen P. J. , Sijbesma Rint P. 
Published: April 2006

AbstractA kinetically inert, reversible coordination polymer (3) was obtained through complexation of dicyclohexylphosphine telechelic poly(tetrahydrofuran) with palladium(II) dichloride. This coordination polymer is unreactive towards palladium(II) dichloride bis(1‐diphenylphosphino)dodecane (4), because ligand dissociation in the coordination polymer is slow. However, upon ultrasonication of solutions of 3 in toluene in the presence of 4, formation of palladium(II) heterocomplexes was observed with 31P NMR spectroscopy. Heterocomplex formation, the consumption of 4, and changes in molecular weight were used to quantify the scission process. In the presence of 60 equivalents of the alkyldiphenylphosphine stopper complex, the reduction in molecular weight was strongly enhanced; over a period of eight hours the weight‐averaged molecular weight was reduced from 1.1×105 to 2.3×104 g mol−1 while 47 % of the palladium(II) complexes in the coordination polymer had been converted into heterocomplexes. These results show that the system of 3 in combination with scavenger 4 is a suitable system to study the efficiency of ultrasound‐induced chain scission of coordination polymers.

Homogene Katalyse in der Chemischen Industrie. Selektivität, Aktivität und Standzeit
Authors: Röper Michael 
Published: April 2006

AbstractDie homogene Katalyse hat sich in der Technik als Ergänzung zur heterogenen Katalyse fest verankert. Eine besondere Domäne sind die C‐C‐verknüpfenden Reaktionen wie Oligomerisierung von Olefinen, Hydoformylierungen, Carbonylierungen und Hydrocyanierungen. In der Feinchemie haben sich enantioselektive Synthesen, vor allem Hydrierungen, sowie Kupplungsreaktionen etabliert und finden zunehmend breitere Anwendung. Wegen des Potentials, Reaktionssequenzen stark zu verkürzen und Abfälle aufgrund der hohen Selektivitäten und der Vermeidung von Koppelprodukten drastisch zu vermindern, trägt die homogene Katalyse zur nachhaltigen Entwicklung der Chemie und einer Verbesserung der Wirtschaftlichkeit bei.
