Cyclopentadienylchromium Complexes of Sulfur

The syntheses are performed either in a Vacuum Atmospheres Drilab or using conventional Schlenk-tube techniques under an atmosphere of dry oxygen-free argon. Tetrahydrofuran (THF), toluene, and n-hexane were distilled under nitrogen from sodium-benzophenone. [CpCr(CO)3]2 is synthesized as described previously. Silica gel used is Merck Kieselgel 60 (35/70 mesh ASTM). Convenient scales of preparation are described below, but the reaction can easily be scaled up several times if necessary.
