Perovskite photovoltaic devices added with tin (Sn) dichloride and copper (Cu) bromide were fabricated characterized. The thin film prepared by an ordinary spin-coating technique using air blowing method in ambient air. A decaphenylcyclopentasilane layer was coated at the surface of perovskite annealed a high temperature 190 °C. Conversion efficiencies short-circuit current densities improved f...

In the title compound, C(16)H(34)N(4) (2+)·2Cl(-)·3H(2)O, the two protonated N atoms in the macrocyclic ring of the dication are located at diagonally opposite positions. There are two intramolecular N-H⋯N hydrogen bonds in the cation. The crystal structure features O-H⋯Cl, O-H⋯O, C-H⋯Cl and N-H⋯Cl hydrogen bonds.

The reduction of titanocene dichloride with dysprosium yields a new titanocene(ii) equivalent without the need for further stabilising ligands. This reagent can be employed in combination with dithioacetals for the olefination of different carbonyl groups and allows for a simplified all-in-one procedure.

The reaction of ethyl 2-ethynylphenylcarbamate derivative with alkenes in the presence of a palladium(II) catalyst, copper dichloride and tetrabutylammonium fluoride (TBAF) produced 2-substituted 3-ethenylindoles during refluxing. The intramolecular cyclization reaction of ethyl 2-ethynylphenylcarbamates, which have an ethenyl part in the ethynyl group, was also used to produce carbazole deriva...

Novel O-ethyl O-heteroaryl 2-chloroethyl phosphonates have been prepared by condensing 2chloroethyl phosphonyl dichloride by the sequential addition of ethanol and –OH and –SH carrying heteroaryls. Attempts of the above reaction with –NH carrying heteroaryl (benzimidazole) furnished a different product than the expected one by different reaction path.

Zirconocene dichloride (Cp(2)ZrCl(2)) has been shown to be an effective catalyst for the transamidation of primary amides with amines in cyclohexane at 80 °C in 5-24 hours. For favourable substrates, the reaction can be performed at temperatures as low as 30 °C.
