摘要：
We report the synthesis of three radical-cation salts of BEDT-TTF from racemic tris(oxalato)ferrate by electrocrystallization in the presence of chiral molecules. In the presence of enantiopure l-(+)-tartaric acid, we observe spontaneous resolution of the labile tris(oxalato)ferrate anion to produce the chiral radical-cation salt alpha-(BEDT-TTF)5[Delta-Fe(C2O4)3].[l-(+)-tartaric acid]2 which contains only the Delta enantiomer of Fe(C2O4)3. Using enantiopure (R)-(-)-3-hydroxytetrahydrofuran as an additive gives alpha-(BEDT-TTF)12[Fe(oxalate)3]2.(H2O)16.ethanol.(R)-(-)-3-hydroxytetrahydrofuran, which includes the chiral guest and contains a racemic mixture of Lambda and Delta enantiomers of Fe(C2O4)3. Enantiopure (S)-phenyloxirane is hydrolyzed to racemic 1-phenylethane-1,2-diol to produce racemic beta"-beta"-(BEDT-TTF)4(H2O/H3O)Fe(C2O4)3.1-phenylethane-1,2-diol.
