formation of [Hpy][Mepy]4[UCl(calix)}3(mu3-O)][UCl6] (6) during the reaction of UCl4 and H2Me2calix, and of [U(Me2calix)(mu3-O)LiCl(THF)}2] (7) during the reaction of 2 with tBuLi. The X-ray crystal structures of 1.2THF, 2.2py, 3.0.25L (L = THF and py), 4.2py, 5, 6.3py and 7.THF have been determined.
UCl4与25,27-二甲氧基-5,11,17,23-四叔丁基杯[4]
芳烃(H2Me2calix)在THF或
吡啶中于80℃反应,得到[UC

L2] [L = THF (1)或
吡啶(2)]。用H2Me2calix在THF或
吡啶中对U(acac)(4)(acac = MeCOCHCOMe)进行类似处理,得到[U(acac)2(Me2calix)](3)。双杯
芳烃化合物[U(Me2calix)(H2calix)](4)是通过将U(OTf)4或U(OTf)3与H2Me2calix在
吡啶中于110℃反应制得的。 110摄氏度时得到[Mepy] [UC
