摘要

Metathesis involving YCl3 and sodium 1,1,1,3,3,3-hexaffuoro-2-propoxide offered a mixed-metal species, YNa3[OCH(CF3)(2)](6)(THF)(3) (1). The reaction between 1 and yttrium and copper derivatives, beta-diketonates and halides, gave access to YNa2 [OCH(CF3)(2)](4)(thd)(THF)(4) (2) and the Na-Cu species, Na2Cu[OCH(CF3)(2)](4)(THF)4 and [NaCu[OCH(CF3)(2)](2)(thd)](m) (5), respectively (thdH = 2,2,6,6-tetramethylheptane-3,5-dione). Alcohol interchange reactions between Y5O(OPri)(13) and fluoroisopropanol led to the isolation of Y[OCH(CF3)(2)](3)L(3) [L = THF (3a) or (PrOH)-O-i (3b)] depending on the solvent, THF or hexane. The various compounds have been characterized by FT-IR, NMR (H-1, C-13, F-19) and mass spectrometry and thermogravimetric analysis. All compounds are volatile; sublimation of the Y-Na or Na-Cu species occurs with retention of the stoichiometry between the metals. The Lewis bases are readily lost during sublimation of compounds 1, 2 and 3a or 3b. [References: 32]
