Tunable aryl alkyl ionic liquids with weakly coordinating bulky borate anion

Concerted steric and electronic effects on α-diimine nickel- and palladium-catalyzed ethylene polymerization and copolymerization

“…Toluene was dried with sodium metal using benzophenone as an indicator and distilled under nitrogen. (COD) PdMeCl (COD = 1,5-cyclooctadiene) [48], (DME)NiBr 2 (DME = 1,2 dimethoxyethane) [49], and sodium tetrakis(3,5-bis(trifluorome thyl)phenyl)borate (NaBArF) [50] were prepared according to previously reported procedures, respectively. Other solvents and chemicals were purchased from Energy Chemicals, and J&K Chemical and used as received.…”

Tailored Palladate Tunable Aryl Alkyl Ionic Liquids (TAAILs)

“…THF and DCM were distilled prior to use. The following compounds were synthesized according to literature procedures: 1 a , 1 b , 1 d , 1 e , 1 f , 1 g , 1 h , 1 i , 1 n , 5 a , 5 b , 1‐(2‐methylphenyl)imidazole, 1‐(4‐fluorophenyl)imidazole, 1‐(2‐methoxyphenyl)imidazole, 1‐(4‐nitrophenyl)imidazole . The following compounds were dried at 100 °C in high vacuum: 1 n , 1 o , 1 p .…”

Tetrakis(pentafluoroethyl)gallate, [Ga(C2F5)4]−, Ionic Liquids

“…The [B(OCH(CF 3 ) 2 ) 4 ] À anion leads to lower viscosity and melting points in comparison to the [NTf 2 ]anion. [16,17] In this work we present TAAILs featuring the recently introduced tetrakis(pentafluoroethyl)gallate anion, [Ga(C 2 F 5 ) 4 ] -. This weakly coordinating anion with gallium as the central atom is highly resistant towards aqueous hydrochloric acid or lithium hydroxide, and is therefore well suited for ionic liquids.…”
