Pentanuclear Gold(I) Cluster with an Axially Chiral Biaryl Center: Synthesis and Chiral Transformation

We synthesized and structurally characterized a novel pentanuclear gold(I) cluster by a Ag(I)-mediated organometallic transformation. The racemic mixture of this pentanuclear gold cluster has been successfully transformed into an enantio-rich hexanuclear

New Indolo[3,2-b]indole based small organic molecules for Organic Thin Film Transistors (OTFTs): A combined experimental and DFT Study

Synthesis of new indolo[3,2-b]indoles (5a- 5j) in presence of Ag-doped ZnO and (Diacetoxyiodo) benzene system under visible-light have been reported. All the new fused linear heterocyclic indolo[3,2-b]indole systems (5a- 5j) thoroughly characterized by spectroscopic methods like mass, UV-visible, NMR and C, H, N elemental analysis. Further, their photophysical properties were carried out by combined experimental and theoretical studies. Thermogravimetric studies are carried out to confirm the thermal stability of molecules. The frontier molecular orbitals of molecules are characterized with the help of cyclic voltammetry. Additionally, the compounds of series 5 were used for the fabrication of organic thin-film transistors, which indicated the hole mobilities in the range of 0.11 – 0.85 cm2/Vs and with on/off ratio 105 on ODTS-SiO2 substrate at 50 °C and are also supported by DFT studies.

Preparation and Reactions of Mono- and Bis-Pivaloyloxyzinc Acetylides

Mono-pivaloyloxyzinc acetylide and bis-pivaloyloxyzinc acetylide were selectively prepared from ethynylmagnesium bromide in quantitative yields. These zinc reagents readily underwent Negishi cross-couplings with (hetero)aryl iodides or bromides as well as subsequent Sonogashira cross-couplings. 1,3-Dipolar cycloadditions of these zinc acetylides with benzylic azides produced zincated and bis-zincated triazoles which were trapped with several electrophiles. An opposite regioselectivity compared to the Cu-catalyzed click-reactions was observed.
