Formation of molecular hydrogen complexes of iron by the reversible protonation of iron dihydrides with alcohols
Abstract
Reversible protonation of cis-FeH2(PP)2[PP = R2PCH2CH2PR2] complexes by ethanol produces the η2-co-ordinated molecular hydrogen complexes trans-FeH(H2)(PP)2+ which readily undergo substitution with loss of H2.
