Abstract
AbstractIsocyanides (isonitriles) are unique organic compounds that contain a formally divalent carbon. Herein, the synthesis of 1,3‐bis(isocyanopropyl)tetramethyldisiloxane was performed by a modified carbylamine method, using a phase transfer agent. Spectral methods (nuclear magnetic resonance [NMR], Fourier transform infrared spectroscopy [FT‐IR], and electrospray ionization mass spectrometry [ESI‐MS]) were used to confirm the structure. Energy gap of 1.86 eV (measured by diffuse reflectance spectroscopy [DRS]), high dielectric permittivity (15 at 10 kHz), and conductivity value in the order of 10−7 S·cm−1 place this compound in the range of wide‐bandgap semiconductors. The synthesis of Pt, Ag, and Fe metal complexes without organic co‐ligands and their catalytic activity were also investigated. The Pt complex was active in hydrosilylation reaction and in reduction of p‐nitrophenol, whereas the Ag complex was found effective in alkaline decomposition of hydrogen peroxide. The Fe complex is a new and cheap heterogeneous hydrosilylation catalyst and also showed very good catalytic behavior in heterogeneous Fenton‐like photodecomposition of Congo Red in various photo‐irradiation conditions, with 100% color removal efficiency after 60 min under sunlight. Thus, a simple path for siloxane‐containing materials with promising applications is open.
