[WIETELMANN ULRICH, LISCHKA UWE, SCHADE KLAUS, PANITZ JAN-CHRISTOPH] DE Methods are disclosed for the production of hydrogen bis(chelato)borates of general formula H[BL1L2] and alkali metal bis(chelato)borates of general formula M[BL1L2], where M = Li, Na, K, Rb, Cs, L1 = -OC(O)-(CR1R2)n-C(O)O- or -OC(O)-(CR3R4)-O-, where n = 0 or 1, R1, R2, R3, R4 independently = H, alkyl, aryl or silyl, L2 = -OC(O)-(CR5R6)n-C(O)O- or -OC(O)-(CR7R8)-O-, where n = 0 or 1, R5, R6, R7, R8 independently = H, alkyl, aryl or silyl, whereby the starting material is mixed in solid form without the introduction of solvents and brought to reaction. For example lithium bis(oxalato)borate, lithium bis(malonato)borate, caesium bis(oxalato)borate, caesium bis(malonato)borate and the mixed salts lithium (lactato, oxalato)borate and lithium (glycolato, oxalato)borate can be produced thus.
