Direct atom transfer vs. ring expansion in reaction of rhenium oxo complexes with cyclooctene epoxides and episulfides

Creator:: Khownium, Kriangsak
Abstract:: The rhenium (V) complex Tp'ReO₂ (Tp' = hydrido-tris-(3,5- dimethylpyrazolyl)borate), generated in situ from PPh₃ reduction of Tp'Re0₃, reacts with small ring heterocycles such as epoxides and episulf ides. The strained trans-cyclooctene ring provides an unusual thermodynamic bias against direct atom transfer, but trans-cyclooctene oxide still produces substantial amounts of trans-cyclooctene....
