Selective Access to Electron Donating Group Substituted (η<sup>5</sup>-cyclohexadienyl)Mn(CO)<sub>3</sub> Complexes by Bimetallic Manganese−Palladium Activation
Unprecedented (η5-cyclohexadienyl)Mn(CO)3complexes bearing an electron-donating group at the end of the π system have been selectively prepared using Pd catalysis and primary, secondary cyclic, and acyclic amines. This catalytic methodology has been extended to O-, S-, and P-based derivatives. The X-ray structure of one coupling product exhibits an unusual conformation in its η5 system.
