Rare-Earth Iodides in Ionic Liquids: The Crystal Structure of [SEt3]3[LnI6] (Ln = Nd, Sm)
摘要:
Crystals of [SEt3](3)[Lnl(6)] (Ln = Nd, Sm) were obtained by the reaction of Lnl(2) with the ionic liquid [SEt3][Tf2N] [Tf2N = bis(trifluoromethanesulfonyl)imide]. The compounds are characterized by octahedral [Lnl(6)](3-) units that are surrounded by a distorted cube of triethylsulfonium cations.
Triethylsulfonium Bistriflimide as the Reaction Medium in Catalyzed and Uncatalyzed Cycloaddition [4 + 2]
摘要:
Triethylsulfonium bistriflimide, [S-2.2.2][NTf2], has been tested and compared with other ionic liquids and molecular solvents as a medium in Diels-Alder reaction between cyclopentadiene and dimethyl maleate. Triflates and chlorides of different metals have been combined with [S-2.2.2][NTf2] and the catalytic activity of the systems formed have been determined. The effect of concentration of the catalysts in sulfonium ionic liquid and reactants on the yield and endo:exo ratio has been established. The representative catalyst-Yb(OTf)(3)center dot xH(2)O in [S-2.2.2][NTf2] has been examined in the reaction of cyclopentadiene with various dienophiles. The use of sulfonium ionic liquids permitted recycling the catalysts. For the best four catalytic systems, the products have been isolated.

Room Temperature Molten Salts Based on Trialkylsulfonium Cations and Bis(trifluoromethylsulfonyl)imide
Symmetric and aliphatic trialkylsulfonium cation form room temperature molten salts (RTMS) with bis(trifluoromethylsulfonyl)imide (TFSI). In particular RTMS based on triethylsulfonium shows low melting point (−35 °C) and the lowest viscosity (30 mPs at 25 °C) of all the TFSI based RTMS as reported so far. The conductivity of 7.1 mS cm−1 at 25 °C is the highest of all the non-chloroaluminate RTMS based on aliphatic onium cations.
对称和脂肪族三烷基锍阳离子与双(三氟甲基磺酰基)亚胺(TFSI)形成室温熔盐(RTMS)。特别是以三乙基锍为基础的室温熔盐(RTMS)显示出较低的熔点(-35 °C)和粘度(25 °C时为30 mPs),是迄今报道的所有以 TFSI 为基础的室温熔盐中粘度最低的。在所有基于脂肪族鎓阳离子的非氯铝酸盐 RTMS 中,25 °C 下 7.1 mS cm-1 的电导率最高。
