The guanidine–quinoline ligand dimethylethyleneguanidinoquinoline (DMEGqu) is able to stabilise bis(chelate) copper complexes in an intermediate geometry between tetrahedral and square‐planar environments. structures of the obtained model entatic state have been investigated solid by single‐crystal X‐ray diffraction solution absorption spectroscopy. dimethylethyleneguanidine (DMEG) unit DMEGqu displays a smaller steric encumbrance than tetramethylguanidine (TMG) counterpart; this allows...
Heteroscorpionate ligands of the bis(pyrazolyl)methane family have been applied in stabilisation terminal copper tosyl nitrenes. These species are highly active intermediates copper-catalysed direct C-H amination and nitrene transfer. Novel perfluoroalkyl-pyrazolyl- pyridinyl-containing were synthesized to coordinate a reactive centre. Four distinct nitrenes prepared at low temperatures by reaction with SO2 tBuPhINTs copper(I) acetonitrile complexes. Their stoichiometric reactivity has...
The electron-transfer abilities of the copper guanidinoquinoline (GUAqu) complexes [Cu(TMGqu)2 ]+/2+ and [Cu(DMEGqu)2 (TMGqu=tetramethylguanidinoquinoline, DMEGqu=dimethylethylguanidinoquinoline) were examined in different solvents. determination electron self-exchange rate based on Marcus theory reveals highest with pure N-donor ligands (k11 =1.2×104 s-1 m-1 propionitrile). This is supported by an examination reorganisation energy using Eyring DFT calculations. low energies nitrile solvents...
Nowadays, the daily work of many research communities is characterized by an increasing amount and complexity data. This makes it increasingly difficult to manage, access utilize data ultimately gain scientific insights based on it. At same time, domain scientists want focus their science instead IT. The solution management store in a structured way enabling easy discovery for future reference usage. An integral part use metadata. With it, becomes accessible its content context name location...
CuI complexes of the form K[(R3 P)Cu(pinF )], in which (pinF )2- is bidentate, oxygen-donating ligand perfluoropinacolate, were synthesized and characterized. Low-temperature oxygenation )(PR3 )] species resulted a trisanionic bis(μ3 -oxo) trinuclear copper(II,II,III) core characterized by UV/Vis spectroscopy (λmax [nm] = 330, 535, 630), cryospray-ionization mass spectrometry, X-band electron paramagnetic resonance (derivative at 3300 G, Δms =2 1500 G). The kinetic behavior trimeric {Cu3 O2...
The influence of functionalized ligands on the electron‐transfer abilities copper guanidinoquinoline complexes as entatic state models has been examined. An electron donating group (OCH 3 ) or withdrawing (Br) was introduced in 6‐position quinoline unit TMGqu and DMEGqu. self‐exchange rates k 11 with these were determined using Marcus cross relation. values are smaller equal to their unsubstituted forms. These results complemented by examination reorganization energies via Eyring theory DFT...

Abstract Terminale Kupfernitrene wurden durch die Verwendung von Bis(pyrazolyl)methan‐Liganden stabilisiert. Diese Spezies sind hochreaktive Intermediate in der C‐H‐Aminierung und im Nitrentransfer. Neuartige Perfluoralkyl‐Pyrazolyl‐ Pyridinyl‐haltige Liganden entwickelt, um ein reaktives Kupfer‐Nitrenzentrum zu koordinieren. Über eine Reaktion mit SO 2 tBuPhINTs Kupfer(I)‐Acetonitril‐Komplexen vier diskrete Kupfertosylnitrene hergestellt. Sie hinsichtlich ihrer Reaktivität Iminierung...
We present a micro-jet sample delivery system for Raman measurements. Compared to cuvette measurements, the observed signal is enhanced by more than one order of magnitude and does not contain distortions from liquid-glass interface. Furthermore, stability repeated measurements due reduced damage effects constantly replenishing sample. This allows study sensitive samples that can only be produced in low concentrations. Our setup consists controlled environment either under vacuum or an...

W niniejszym tekście skoncentrujemy się, wbrew obecnym trendom w literaturze przedmiotu, na jednej z rzadziej dyskutowanych pod kątem etycznym i społecznym postaci ulepszania natury ludzkiej, to jest udoskonalaniu ludzkich możliwości przy pomocy innowacyjnych urządzeń technicznych. kontekście interfejsów mózg-komputer przyjrzymy się najpierw działaniu możliwościom, a następnie potencjalnym problemom związanym jednym ciekawszych wynalazków ostatnich lat – tzw. „inteligentnymi okularami”,...
