Methane Oligomerization in the Gas Phase by Third-Row Transition-Metal Ions.(Reannouncement with New Availability Information)

摘要

Methane is spontaneously dehydrogenated in the gas phase by many metal ions ofthe 5d transition series. In most cases, the product MCH2+ undergoes further reactions, leading eventually to products such as WC8H16+, which must contain at least six carbon-carbon bonds. Reactivity patterns of the third-row transition metals are rationalized in terms of their electronic structure, including the interesting unreactive ions La+, Hf+, and Re+.
