Safety of Chloro(1,5-cyclooctadiene)copper(I) dimer. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Chloro(1,5-cyclooctadiene)copper(I) dimer, is researched, Molecular C16H16Cl2Cu2, CAS is 32717-95-6, about Regioselective Transformation of O-Propargylic Arylaldoximes to Four-Membered Cyclic Nitrones by Copper-Catalyzed Skeletal Rearrangement. Author is Nakamura, Itaru; Araki, Toshiharu; Zhang, Dong; Kudo, Yu; Kwon, Eunsang; Terada, Masahiro.
(E)-O-Propargylic arylaldoximes were regioselectively converted, in the presence of copper catalysts, into their corresponding four-membered cyclic nitrones in good to excellent yields. E.g., in presence of [CuCl(cod)]2, reaction of (E)-O-propargylic arylaldoxime I gave 82% (E)-cyclic nitrone II. The reactions proceeded via a tandem [2,3]-rearrangement and 4π-electrocyclization of the N-allenylnitrone intermediate and involved cleavage of the carbon-oxygen bond.
