Safety of Chloro(1,5-cyclooctadiene)copper(I) dimer. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Chloro(1,5-cyclooctadiene)copper(I) dimer, is researched, Molecular C16H16Cl2Cu2, CAS is 32717-95-6, about Gold catalyzed rearrangements of strained small ring hydrocarbons. Author is Meyer, Lueder U.; de Meijere, Armin.
Diademane (I) underwent Au-catalyzed rearrangement to give 50% snoutene (II) together with 5% of the thermally rearranged product, triquinacene. At elevated temperatures, II underwent Au-catalyzed rearrangement to basketene (III), which subsequently thermally rearranged to Nenitzescu’s hydrocarbon. Similar catalysis of the diene IV, gave >90% tetrahydronaphthalene.
