Cyclopropane isopropenyl
The first example of cyclopropane being activated by a metal complex was reported in 1955, involving the reaction of cyclopropane and hexachloroplatinic acid. This reaction produces the polymeric platinacyclobutane complex Pt(C3H6)Cl2. The bis(pyridine) adduct of this complex was characterized by X-ray crystallography. The electrophile Cp*Ir(PMe3)(Me)OTf reacts with cyclopropane to give the allyl complex: WebCyclopentane, 1-acetoxymethyl-3-isopropenyl-2-methyl- C12H20O2 CID 539231 - structure, chemical names, physical and chemical properties, classification, patents ...
