Abstract

The present invention relates to boron and aluminum complexes, to the preparation thereof, and to the use thereof for solubilizing ionic compounds. The complexes have one of the following formulae:in which D represents B or Al; R1 represents R, RF, NO2, CN, C(═O)OR, RSO2, or RFSO2; —X1—, —X2—, —X3— and X4 each represent a divalent group >C═O, >C═NC≡N, >C═C(C≡N)2, >CR2R3 or >SO2; —Y1—, —Y2— and —Y3— each represent a divalent group —O—, >N(C≡N), >N(CORF), >N(SO2R4), >NR4, >N(COR4) or >N(SO2RF); R, R2 and R3 each represent H, an alkyl group, an aryl group, an alkylaryl group, an arylalkyl group, an oxaalkyl group or an alkenyl group; R4 represents an alkyl group, an aryl group, an alkylaryl group, a heteroaryl group, an arylalkyl group, an oxaalkyl group, an alkenyl group or an RFCH2— group; RF is a perfluoroalkyl group, a partially fluorinated alkyl group, or a partially or totally fluorinated phenyl group; each of the R′2 and R′3 groups represents R or F.
