Abstract

All in the family: [(η4-R4Si4)Fe(CO)3] 2 (R=SiMetBu2) represents a neutral silicon congener of a (cyclobutadiene)tricarbonyliron complex and was synthesized by the reaction of the dibromocyclotetrasilene R4Si4Br2 1 with Na2[Fe(CO)4]. The tetrasilacyclobutadiene ligand in 2 has stronger π-donating properties than the cyclobutadiene ligand in the parent complex [(η4-H4C4)Fe(CO)3].
