Boron or aluminum complexes

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; Rrepresents R, R, NO, CN, C(═O)OR, RSO, or RSO; —X—, —X—, —X— and Xeach represent a divalent group >C═O, >C═NC≡N, >C═C(C≡N), >CRRor >SO; —Y—, —Y— and —Y— each represent a divalent group —O—, >N(C≡N), >N(COR), >N(SOR), >NR, >N(COR) or >N(SOR); R, Rand Reach represent H, an alkyl group, an aryl group, an alkylaryl group, an arylalkyl group, an oxaalkyl group or an alkenyl group; Rrepresents an alkyl group, an aryl group, an alkylaryl group, a heteroaryl group, an arylalkyl group, an oxaalkyl group, an alkenyl group or an RCH— group; Ris a perfluoroalkyl group, a partially fluorinated alkyl group, or a partially or totally fluorinated phenyl group; each of the R'and R′groups represents R or F.
