Two new multiply methylthio-substituted ferrocene ligands 1,1′,2-tris- and 1,1′,2,2′-tetrakis-(methylthio)ferrocene have been prepared by a simple, single-step procedure; substitution of the ferrocenyl rings occurs in an adjacent fashion leading to versatile, multidentate ligand behaviour as demonstrated by their reaction with a tungsten carbonyl centre.
