The fluorinated alcohol perfluoropropyl carbinol was used to give the product sodium tetrakis(2,2,3,3,4,4,4‐heptafluorobutoxy)borate, Na[B(OCH 2 (CF 2) 2 CF 3) 4] (1 c), in excellent yield (81 %). Unlike 1 a and 1 b, no DME was detected in the 1 H NMR spectrum, with just the CH 2 signals observed at 3.88 ppm.Web
