摘要：

(C5Me5)2Sm(THF)2 reacts with 1,2-epoxybutane in toluene to form, in addition to the toluene soluble [(C5Me5)2Sm]2(mu-O), 1, the hexane soluble [(C5Me5)2Sm(THF)]2(mu-O), 2. In hexane, 2 loses THF to form 1 as a precipitate, but 1 cannot be converted to 2 by addition of THF at room temperature. Compound 1 does convert to 2 in low yield in THF at reflux. The reaction of (C5Me5)2Sm(phthalan) with 1,2-epoxybutane generates 1 and a phthalan analog of 2, [(C5Me5)2Sm(phthalan)]2(mu-O), 3. Compound 2 reacts with Me3CCN to form [(C5Me5)2Sm(NCCMe3)]2(mu-O), 4, by displacement of THF.
