Reactivity of electron donor-acceptor complexes. Part 9.—Isomerization of butene

摘要: The isomerization of butene was studied over various electron donor-acceptor (EDA) complexes for which the behaviour hydrogen had been examined. relative catalytic activity EDA cis-2-butene to 1-butene and trans-2-butene closely connected with that H2—D2 exchange reaction, activities both reactions depending upon affinity acceptor molecules. sodium has a maximum in region 0–0.6 eV molecules is small or negligible either stronger weaker magnesium, on other hand, showed 1.2 1.6 affinity. Accordingly, donor gives optimal acceptor. cis-trans also aromatic compounds SbCl5, an acceptor; ionization potential (about 7.0 eV) donors demonstrated.
