Thermoanalytical and preparative investigations of the decomposition of potassium perfluoroorganyl(fluoro)borate salts, K[RFBF3] (RF = perfluoroalkyl, -alkenyl, -alkynyl, and -aryl groups) and K[(RF)2BF2] (RF = C 6F5 and C6F13)

Potassium perfluoroalkenyl(fluoro)borates, K[RFBF3], (RF = CF2C(CF3), cis-CF3CFCF, and cis-C6F13CFCF) decomposed at 208-225 C (Tmax, dTG). The K[RFBF3] salts (RF = C 3F7, C6F13, trans-CF 3CFCF, and trans-C4F9CFCF) decomposed at 273-312 C (Tmax, dTG). Both groups of salts formed volatile polyfluoroorganics and K[BF4] as solid residue. The preparative thermolysis of selected prototypical salts K[RFBF3] showed that the polyfluoroorganics consisted of a mixture of internal perfluorohexenes, C6F12, and 1-H-tridecafluorohexane, C6F13H, in case of K[C6F13BF 3], and of perfluorooctynes, C8F14, and cis-C6F13CFCFH in case of K[cis-C6F 13CFCFBF3]. The salts K[(C6F5) 2BF2] and K[RFBF3] (RF = CF3CC, CF3CFCFCC, C6F5CC, C 6F5, 2,3,5,6-C5NF4) decomposed in the temperature range 249-337 C (Tmax, dTG) and mainly resulted in non-volatile polyfluoroorganics besides K[BF4]. The reaction path of the thermolysis of perfluoroalkyl-, perfluoroalkenyl-, and perfluorophenyl(fluoro)borates is discussed and compared with that of perfluorocarboxylates.
Thermal decomposition of 4-fluorobenzenediazonium perfluoroorganyl(fluoro) borates, [4-FC6H4N2]Y (Y = RFBF 3 (RF = C6F5, C6F 13, trans-C4F9CFCF, cis-C6F 13CFCF, CF3CC) and (C6F13) 2BF2)

Heating of the neat salts [4-FC6H4N 2][RFBF3] (RF = C6F 5, C6F13, trans-C4F9CFCF, cis-C6F13CFCF, CF3CC) or in solid mixtures with NaF gives the principal product 1,4-C6F2H4 besides RFBF2 or Na[RFBF3], respectively. Thermolysis of [4-FC6H4N2] [(C6F13)2BF2] in NaF results in 1,4-C6F2H4, Na[BF4], Na[(C 6F13)2BF2], and a new type of product, the isomer Na[C6F13CF(BF3)C 5F11].
