Transition-metal complexes of methylenecyclopropanes: ring-opening reactions promoted by palladium(II)
Abstract
A variety of stable 1,2-η-bonded methylene cyclopropane complexes of RhI, IrI, Pto, and PtII are reported; isomers of Feist's acid dimethyl ester react with PdCl2(MeCN)2 to yield 1,3-enyl complexes of palladium-(II); stable alkyl complexes of PdII; containing β-hydrogen atoms are reported, and their stability is discussed.
