摘要：

Treatment of Cp*TaCl4 (1) with two equivalents of a 2-butenyl Grignard reagent in THF afforded the tantalum-1,3-butadiene complex Cp*TaCl2(C4H6) (2a), Similarly, the reaction of 1 with methylated-allyl anions gave the corresponding diene complexes Cp*TaCl2(diene) (2b: diene = isoprene, 2c: 2,3-dimethyl-1,3-butadiene, 2d: 1,3-pentadiene).
