The reaction of formic acid methyl ester in the superacidic system XF/MF5 (
X = H, D: M = As, Sb) leads to the hydroxy methoxy carbenium hexafluorometa
llates. The very hydrolysable and thermo labile salts are characterized by
vibrational and NMR spectroscopic methods. Under inert conditions they are
stable at -20 degrees C for some weeks. HC(OCH3)(OH)+AsF6- crystallizes in
the monoclinic space group P2(1)/c (No. 14) with a = 5.275(1) Angstrom, b =
11.059(1) Angstrom, c = 12.113(1) Angstrom und beta = 96.64(1)degrees and
four formula units per cell.
