Eine Eintopfsynthese eines CAAC-stabilisierten, unsymmetrischen, cyclischen Diborens wurde mittels Zweielektronenreduktion CAAC-Addukts von B2Br4(SMe2)2 entwickelt. Theoretische Studien offenbarten, dass dieses Diboren einen signifikant geringeren HOMO-LUMO-Abstand als bisher beschriebene NHC- und Phosphan-stabilisierte Diborene besitzt. Die Komplexierung des mit [AuCl(PCy3)] lieferte zwei Dibo...

BACKGROUND Aryl sulfides have significant importance from biological and pharmaceutical aspects. Transition metal-catalyzed carbon-sulfur cross-coupling reaction represents an important tool for the synthesis of sulfides. Among various transition metals, copper salts or oxides have found vast applicability. RESULTS A simple procedure for the preparation of poly-ionic amberlite resins embedded...

This paper starts with developing kinematic and dynamic model of a snake shape robot in serpentine locomotion and finishes with actual experimentation. At the beginning the symmetrical and unsymmetrical serpenoid curves are introduced. Kinematics and dynamics of a snake robot on flat and inclined surfaces are obtained for a general n-link robot. SimMechanics toolbox of MATLAB software is employ...

1:1 and 1:2 lead(II) complexes with 2,9-dimethyl-1,10-phenanthroline (Dmphen), {[Pb(Dmphen)(NO3)n] and [Pb(Dmphen)2(ClO4)2]} have been synthesized and characterized by CHN elemental analysis, IR, 1H NMR, 13C NMR and 207Pb NMR spectroscopy. The structure of these complexes was confirmed by X-ray crystallography. The single crystal X-ray data of [Pb(Dmphen)(NO3)n] show the complex to be polymeric...
