摘要：
Reaction of [η5:σ-Me2C(C5H4)(C2B10H10)]Ru(NCCH3)2 (1) with R1C≡CR1(R1 = Et, Ph) in toluene at 80 °C yielded organoruthenium cyclobutadiene complexes [η5:σ-Me2C(C5H4)(C2B10H10)]Ru(-4-C4R14) in >80% yield. Treatment of 1 with diynes R2C≡C(CH2)3C≡CR2 (R2 = Me, Et) in toluene at room temperature yielded ruthenacyclopentatrienes [η5:σ-Me2C (C5H4)(C2B10H10)]Ru[=C2(R2)2C2(CH2)3] in >85% yield. These new complexes were fully characterized by various spectroscopic techniques, elemental analyses and single-crystal X-ray diffraction studies. The possible reaction mechanism was proposed.
