A named reaction displaying E1cB elimination mechanism is the Boord Olefin Synthesis . Being able to distinguish between different elimination reaction mechanisms (E2, E1, E1cB) is often difficult and involves the study of predicts that the carbanion in this example is stabilized by only 2.8 Kcal / Mol (11.7 KJ /mol) and only when Solvatation of all the chemical species with water is taken into account. The same fluoride substrate but as a free Pyridine does not have this stabilization and the reaction proceeds by a Concerted one-step E2 Reaction Mechanism . When the leaving group in the methylated pyridine compound is Chlorine instead of fluoride the reaction mechanism is also E2 because now the carbon to chloride bond is too weak. REFERENCES |
