guanidinium salts [(Me2N)2CNHSiMe3]Hal (Hal Cl (1), Br (2)) and [(Me2N)2CN(SiMe3)2]Hal (Hal Cl (3), Br (4), I (5)), respectively, involving tetracoordinate silicon. No reaction occurs with Me3SiF. The same ionic species are present in CHCl3 or CH3CN solutions (IR, 1H, 29Si NMR), thus establishing for the first time, the formation of an ionic solid derivative of Me3SiCl stable towards dissociation. Reaction
Two series of super-base-derived hypergolic ionic liquids were synthesized, which all exhibit good hydrolytic stability to heat and expected hypergolic properties upon contact with WFNA.
