Atypical carbon-carbon bond scission and deoxygenation in the protonation of tungsten-eta(1)-oxabicyclic compounds

摘要

[[abstract]]Treatment of tungsten-eta(1)-7-oxabicyclo[2.2.1]heptadiene and -eta(1)-7-oxabicyclo[2.2.1]heptene with CF3SO3H leads to atypical carbon-carbon bond scission and deoxygenation; the reaction intermediates in the bond scission involves a tungsten-eta(1)-2-hydrofurylium cation.
