The oN (cI) F+ AsF6-and ON (CFJF+ AsF; salts are prepared by oxidative fluorination of ONCI and ONCF3 with N2F+ AsF (. Methylation of ONCF, with CH3F and AsFJ gives ON (cH3) CF3+ AsF6-, which in the solid state exists as the enol tautomer hydroxylimmonium salt HON (CH2) CF3+ AsF6-, triclinic, of space group PT with a= 5.063 (I) A, b= 7.757 (3) A, c= 10.429 (2) A, CY= 86.75 (2) O, fl= 89.34 (2) O, and y= 74.12 (2)". The framework of the ...
