| Abstract
| - Potassium bis(perfluoroalkyl)dimethoxyborate salts, K[(CnF2n+1)2B(OMe)2] (n = 3, 4, 6), were prepared in 60−76% yield by the reaction of (perfluoroalkyl)lithium with chlorodimethoxyborane and subsequent metathesis of the cation with KF. Reactions of K[(CnF2n+1)2B(OMe)2] with 42−73% aqueous HF resulted in the salts K[(CnF2n+1)2B(OR)F] (R = H, CH3), which were converted into K[(CnF2n+1)2BF2] by the treatment with anhydrous HF. Metathesis of potassium salts with [NMe4]OH in water yielded the corresponding borates [NMe4][(CnF2n+1)2BF2].
