Draw the Lewis dot structure for CH4, showing the bonds and the VSEPR shape. Indicate the name of the shape. How many lone pairs of electrons are present? Draw the Lewis dot structure for H2O and a second structure showing the bonds and the VSEPR shape. What is the name of the shape?
Three thiostannates (H2en)2Sn2S6?en 1, (Hen)4Sn2S6 2 (en = ethylenediamine, a known compound) and [(H2hmda)3(Hhmda)2](Sn2S6)2 3 (hmda = hexamethylenediamine) were prepared using SnCl4?5H2O and S8 as starting materials in alkylenediamine solutions under mild solvothermal conditions...
Different kinds of Hantzsch ester 1,4‐dihydropyridines were oxidatively aromatized to their corresponding pyridine derivatives by KBrO3/SnCl4·5H2O system in refluxing CH3CN. The products were obtained in high to excellent yields.doi:10.1081/SCC-200049787Behzad Zeynizadeh...
