| Abstract: | The synthesis and characterization of the lariat-silacrown ether (Sila15NH??IUPAC name: 3-1-1-(3-aminopropyl)-2,5,8,11,14-pentaoxa-1-silacyclotetradec-1-yl] oxy]-2,5,8,11,14-pentaoxa-1-silacyclotetradec-1-yl]propan-1-amine) and its complex with copper(II) ion, Cu(II)?CSila15NH, are reported in this work. Tetraethylene glycol, 3-aminopropyl triethoxysilane and metallic sodium were employed as precursors and the lariat-silacrown ether obtained in a good yield (64?%) was characterized by elemental analysis, infrared spectroscopy (FTIR) and nuclear magnetic resonance of 1H, 13C and 29Si. The Cu(II)?CSila15NH was characterized by elemental analysis and FTIR. The straightforward Cu(II) complex formation suggests this property could be explored for analytical purposes. |
