Using Silicon NMR Spectroscopy To Analyze Compounds
What can you do with 29Si?
Follow the hydrolysis of alkylalkoxysilanes and the subsequent condensation reactions. 29Si NMR differentiates the silanol monomers and the M-structures, D-structures, and T-structures of the oligomers
Did You Know?
Silicon, often thought of as inorganic, it is a vital element for many life forms. Algae (diatoms) convert about six billion metric tons of silicon into silica each year. Silicon also plays important roles in grasses, trees, and bone.
Despite this, the carbon-silicon (C-Si, organosilicon) bond does not exist in nature. Only in the lab have chemists devised synthetic routes to organosilcons. This has led to silicones, organofunctionalized silanes and other valuable materials. Continued R&D and commercialization has resulted in a wide range of industrial and consumer applications.
In 2016 researchers reported using modified enzymes to catalyze the formation of the C-Si bond. This opens the possibility of using biomolecules to produce commodity and specialty organosilicons rather than toxic or expensive catalysts.
