Synthesis, Characterization and Structure of an Iron-silyl Complex Containing Bis(silyl) Ligand Based on O-Heterocyclic Aromatics

Abstract

The bis-(silyl)ligand-based on O-heterocyclic aromatic backbone DBFsil-H2 (1) were prepared by dilithiation of the 4,5-positions of dibenzofuran using n-BuLi in presence of tetramethyl ethelenediamine (TMEDA) followed by addition of chlorodimethylsilane. UV irradiation of Cp*Fe(CO)2Me and 1 in pentane produced Cp*Fe(DBFsilH)(CO)2 (2). X-ray diffraction analysis ensured the structure of complex 2 along with the rigid nature of the dibenzofuran core.
