Iron piano-stool phosphine complexes for catalytic hydrosilylation reaction
摘要:
A family of six cyclopentadienyl-iron carbonyl complexes bearing phosphine ligands (PPh3, PMe2Ph and PCy3) with iodide or PF6 as a counter-anion were prepared and used as catalysts for the hydrosilylation of carbonyl derivatives. Aldehydes were reduced at 30 degrees C, using PMHS as the silane, whereas ketones were reduced at 70 degrees C using PhSiH3. (C) 2011 Elsevier B.V. All rights reserved.
