Evolving View of Natural Flavors
All natural is a common claim on food in the US and other regions, but what does this really mean?
Tetrakis(dimethylamino)ethylene (TDAE)
In 2001, Professor William Dolbier, Jr., at the University of Florida reported1 an approach to nucleophilic trifluoromethylation based on the generation of a trifluoromethyl anion using CF3I in the presence of a powerful twoelectron reductant, tetrakis(dimethylamino)ethylene (TDAE)
High-Performance Quantitative H-1 NMR
