The cleavage of decanethioacetate (C10SAc) has been studied by (1)H nuclear magnetic resonance (NMR) spectroscopy and scanning tunneling microscopy (STM) imaging of in situ prepared decanethiolate self-assembled monolayers (SAMs) on Au(111). Solutions of C10SAc (46 mM) and previously reported cleavage reagents (typically 58 mM) in CD(3)OD were monitored at 20 degrees C by NMR spectroscopy. Clea...

Herein, we have reported the facile synthesis of various benzimidazole / benzothiazole by using DBU-Iodine-Iodide as a green and simple catalyst. The R2NH+I3 complexes been formed reacting an aqueous mixture ammonium iodide molecular iodine with solution amine. structure has confirmed spectroscopic techniques. prepared amine-iodine screened catalyst in benzothiazoles. Among DBUH+I3complex found...

Dimethyl carbonate (DMC) and glycidol are considered industrially important chemical entities there is a great benefit if these moieties can be synthesized from biomass-derived feedstocks such as glycerol or its derivatives. In this report, both DMC were in an integrated process derived 1,3-dichloro-2-propanol CO2 through metal-free reaction approach at mild conditions. Initially, the chlorinat...
