Terminal ruthenium carbido complexes as σ-donor ligands. Chemical Communications (Cambridge, United Kingdom) 2002
, (21), 2524-2525.
The terminal carbido ligand of (PCy3)2(Cl)2RuC (2, prepd. from reaction of (PPh3)2(Cl)2Ru:C(CHCO2Me)2 with PCy3) coordinates to other metal centers in a σ-donor fashion, as in (PCy3)2(Cl)2Ru≡C-Pd(Cl)2(SMe2) (4) and (PCy3)2(Cl)2Ru≡C-Mo(CO)5. The crystal structures of 2, 4, and PdCl2(SMe2)2 were detd. [on SciFinder(R)]
