One type of this reaction is performed using potassium tert-butoxide and has a deuterium isotope effect greater than one.
In the catalytic cycle of Wilkinson's catalyst, the product is evolved after a reductive form of this type of reaction. When performed in a cyclohexane ring, one type of this reaction can be performed on a pair of substituents in the axial position. One type of this reaction is performed using potassium tert-butoxide and has a deuterium isotope effect greater than one. One type of this reaction uses an initial step of exhaustive methylation and generates (*) the less-substituted product, though most types of this reaction generate the most substituted product according to Zaitsev's rule. Another type of this reaction competes with SN1 and results from the deprotonation of a carbocation, creating an alkene, while another requires an antiperiplanar configuration. For 10 points, name this type of reaction whose mechanisms include E1 and E2, in which a group is kicked off a molecule.
