Reduction-induced hapticity increase in a silacycle-bridged biaryl-based ligand coordinated to an iron center

Abstract

An Fe(II) bromide complex supported by a bidentate phosphine ligand and an η¹(C)-coordinated six-membered silacycle-bridged biphenyl-based ligand is converted upon reduction into an Fe(I) complex in which the hapticity of the silacycle-based ligand increases from η¹ to η⁵.
