WebJan 14, 2015 · Tetrakis(dimethylamino)ethylene (TDAE) is a reducing agent which reacts with halogenated derivatives to generate an anion under mild conditions via two sequential transfers of one electron [17,18,19].Through this strategy, we have developed many reactions between nitrobenzylic substrates and a series of electrophiles such as … WebStability . Aromaticity is a chemical property describing the way in which a conjugated ring is more stable than would be expected by the stabilization of conjugation alone.Anti-aromatic is more unstable that would be predicted. Most compounds prefer to be _____ (low/high energy). If an anti-aromatic molecule can twist so that the p orbitals are no longer …
