Abstract
- While the 1 : 1 reaction of C4-trichlorosilyl-functionalized N-heterocyclic carbene (NHC) (2) with [(η<superscript>5</superscript>-C<subscript>5</subscript>H<subscript>4</subscript>Li)<subscript>2</subscript>Fe]<subscript>3</subscript>[TMEDA]<subscript>2</subscript> (3) gives C4-sila[1]ferrocenophane-substituted NHC (4), C4-ferrocenylsilyl-bridged bis-NHC (6) is synthesized by combining 3 with C4-chlorodimethylsilyl-functionalized NHC (5) in a 1 : 2 ratio, (compound 5 is prepared by reaction of the anionic N-heterocyclic dicarbene (NHDC) [:C{[N(2,6-Pr<superscript>i</superscript><subscript>2</subscript>C<subscript>6</subscript>H<subscript>3</subscript>)]<subscript>2</subscript>CHCLi}]<subscript>n</subscript> (1) with Me<subscript>2</subscript>SiCl<subscript>2</subscript>). In addition, ligand 4- and 6-based GeCl<subscript>2</subscript> complexes (7 and 8) are also synthesized. Compounds 4–8 have been characterized by <superscript>1</superscript>H, <superscript>13</superscript>C, and <superscript>29</superscript>Si NMR spectroscopy and single crystal X-ray diffraction.
