Pentaalkylmethylguanidinium methylcarbonates – versatile precursors for the preparation of halide-free and metal-free guanidinium-based ILs

“…Indeed, all guanidinium cations are known to show a propellershaped structure (Scheme 6) both in solution 27, 18 and in the solid state. 28,29 This deviation from a co-planar orientation of the sp 2hybridized nitrogen atoms is energetically advantageous because of the steric repulsion even of small substituents.…”

Hexaethylguanidinium Salts

“…The crystal structures of these new compounds were determined by single-crystal X-ray diffraction. The known chloride 6 [19] is included for comparison.…”

“…Some hexaalkylguanidinium salts, which are liquid at room temperature, have been considered as novel reaction media for organic syntheses [16][17][18]. Thus far, only the crystal structure of HEG chloride has been reported [19], although crystal structures of several other hexaalkylguanidinium salts have been described in recent years [20][21][22][23][24][25][26][27][28][29].…”
