Source of material In an argon atmosphere, methyl vinyl ketone (23 271 μπιοί) was added dropwise to a solution of (thi)2Zr(THF)(>; 2 -Me 3 SiC 2 SiMe3) (155 mg, 271 //mol) in THF (ca. 10 mL). The green solution changed to yellow immediately. All volatiles were removed in vacuo. The residue was dissolved in 3 mL
