Abstract
- Reaction of carbene-stabilized disilicon ( 1) with Fe(CO)<subscript>5</subscript> gives the 1:1 adduct L:SiSi[Fe(CO)<subscript>4</subscript>]:L (L:=C{N(2,6-Pr<superscript> i</superscript><subscript>2</subscript>C<subscript>6</subscript>H<subscript>3</subscript>)CH}<subscript>2</subscript>) ( 2) at room temperature. At raised temperature, however, 2 may react with another equivalent of Fe(CO)<subscript>5</subscript> to give L:Si[μ-Fe<subscript>2</subscript>(CO)<subscript>6</subscript>](μ-CO)Si:L ( 3) through insertion of both CO and Fe<subscript>2</subscript>(CO)<subscript>6</subscript> into the Si<subscript>2</subscript> core, which represents the first experimental realization of transition metal-carbonyl-mediated cleavage of a SiSi double bond. The structures and bonding of both 2 and 3 have been investigated by spectroscopic, crystallographic, and computational methods. [ABSTRACT FROM AUTHOR]
