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: n n n n n n n n n n in which D represents B or Al; R 1 represents R, R F , NO 2 , CN, C(═O)OR, RSO 2 , or R F SO 2 ; —X 1 —, —X 2 —, —X 3 — and X 4 each represent a divalent group >C═O, >C═NC≡N, >C═C(C≡N) 2 , >CR 2 R 3 or >SO 2 ; —Y 1 —, —Y 2 — and —Y 3 — each represent a divalent group —O—, >N(C≡N), >N(COR F ), >N(SO 2 R 4 ), >NR 4 , >N(COR 4 ) or >N(SO 2 R F ); R, R 2 and R 3 each represent H, an alkyl group, an aryl group, an alkylaryl group, an arylalkyl group, an oxaalkyl group or an alkenyl group; R 4 represents an alkyl group, an aryl group, an alkylaryl group, a heteroaryl group, an arylalkyl group, an oxaalkyl group, an alkenyl group or an R F CH 2 — group; R F 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. |
