Conversion of salts Li[(C6HnF5-n)B(OMe)(3)] (n = 0, 1) into (Li center dot DME)[(C6HnF5-n)(2)B(OMe)(2)] was studied in dichloromethane-DME solution. The observed rate constants k decrease from (21.4 +/- 0.9) x 10(-3) l mol(-1) s(-1) (Li[C6F5B(OMe)(3)]) over (6.99 +/- 0.11) x 10(-3) l mol(-1) s(-1) (Li[(2,3,5,6-C6HF4)B(OMe)(3)]) to (2.94 +/- 0.05) x 10(-3) l mol(-1) s(-1) (Li[(2,3,4,6-C6HF4)B(OMe)(3)]), while Li[(2,3,4,5-C6HF4)B(OMe)(3)] does not undergo any transformation. Hydrolysis of (Li center dot DME)[(C6HnF5-n)(2)B(OMe)(2)] leads to corresponding borinic acids, whereas treatment of them with aqueous solution of M[HF2] (M = Bu4N, K) acidified with HF results in M[(C6HnF5-n)(2)BF2] in high yields.
