Abstract: The transient intermediate η2-cyclopropene/bicyclobutane niobium complex [TpMe2Nb(η2-c-C3H4)(MeCCMe)] A, generated by an intramolecular β-H abstraction of methane from the methyl cyclopropyl complex [TpMe2NbMe(c-C3H5)(MeCCMe)] (1), is able to cleave the CH bond of a variety of unsaturated… read more here.
