Synthesis and physical properties of tris(dialkylamino)cyclopropenium dicyanamide ionic liquids.

ABSTRACT: The synthesis and properties of 16 tris(dialkylamino)cyclopropenium (TDAC) cations with the dicyanamide (DCA) anion, [N(CN)₂]^-, are described. D _3h- and C _3h-symmetric cations ([C₃(NR₂)₃]DCA (R = Me, Et, Pr, Bu, Pent, Hex, Dec) and [C₃(NRMe)₃]DCA (R = Bu, St), respectively) were synthesised by reaction of C₃Cl₅H with the corresponding amine. Reaction of the alkoxydiaminocyclopropenium salt [C₃(NEt₂)₂(OMe)]⁺ with amines led to a series of C _2v-symmetric salts [C₃(NEt₂)₂(NR₂)]DCA (R = Me, Bu, Hex) and two C _s-symmetric salts and [C₃
