High-Yield Synthesis of Medium and Large Platinacycloalkanes from Bis(alkenyl) Precursors

摘要

Metallacycloalkanes are an important class of compounds which have been known for many years to be key intermediates in useful catalytic reactions. For example, metallacyclobutanes are known to be present in the alkene metathesis reaction. More recently, metallacycloheptanes were first implicated, then proven to be involved in ethylene trimerization. There has been interesting discussion and a belief that the formation of nine-membered and other larger metallacycloalkane rings is unlikely.
