Abstract Complex [( DIPeP BDI)Ca] 2 (C 6 H ), with a C 2− dianion bridging two Ca 2+ ions, reacts benzene to yield (biphenyl) biphenyl ( BDI=HC[C(Me)N‐DIPeP] ; DIPeP=2,6‐CH(Et) ‐phenyl). The complex was also prepared by reacting ) or reduction of BDI)CaI] KC 8 in presence biphenyl. Benzene‐benzene coupling observed when the deep purple product ball‐milling DIPP BDI)CaI(THF)] K/KI extracted (DIP...
This paper describes the synthesis of barium copper silicate using agglomeration of BaD, CuD, SiOz and borax. The synthesized pigments were then investigated by using X-ray diffraction (XRD) and scanning cleeton microscopy (SEM) techniques. The alkaline oxides, earth alkaline oxides, etc. can reduce the intensity of XRD lines of the samples. In order to confirm the existence of barium co...
Laser induced electronic excitations that spontaneously emit photons and decay directly to the initial ground state (``optical cycling transitions'') are used in quantum information precision measurement for initialization readout. To extend this primarily atomic technique large, organic compounds, we theoretically investigate optical of alkaline earth phenoxides their functionalized derivative...
Mechanochemistry of fluoride solids: from mechanical activation to mechanically stimulated synthesis
Abstract This lecture text is focused on the comparatively young field of mechanochemistry fluoride solids, considering both their mechanical activation and mechanochemical synthesis. Beside a literature survey, synthesis binary fluorides MF 2 , 3 complex MMgF 4 solid solutions M x b 1− F or Ln 2+ (Ln: Y, Eu) fluorine-containing coordination polymers presented. Owing to interesting potential ap...
Scientists have witnessed significant breakthroughs in s-block metal chemistry. Over the past few years, several applications catalysis associated with alkaline-earth catalysts been established owing to their abundance and lower cost. These proved be essential alternatives transition catalysts. Several research groups recognized importance of magnesium complexes as highly active reduction a ser...
