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 α-(BEDT-TTF)[Δ-Fe(CO)].[l-(+)-tartaric acid] which contains only the Δ enantiomer of Fe(CO). Using enantiopure ()-(-)-3-hydroxytetrahydrofuran as an additive gives α-(BEDT-TTF)[Fe(oxalate)].(HO).ethanol.()-(-)-3-hydroxytetrahydrofuran, which includes the chiral guest and contains a racemic mixture of Λ and Δ enantiomers of Fe(CO). Enantiopure ()-phenyloxirane is hydrolyzed to racemic 1-phenylethane-1,2-diol to produce racemic β"-β"-(BEDT-TTF)(HO/HO)Fe(CO).1-phenylethane-1,2-diol.
我们报道了在手性分子存在下，通过电结晶由外消旋三（草酸根）铁酸盐合成三种BEDT-TTF自由基阳离子盐。在对映体纯的L-(+)-酒石酸存在下，我们观察到不稳定的三（草酸根）铁酸根阴离子自发拆分，生成手性自由基阳离子盐α-(BEDT-TTF)[Δ-Fe(CO)].[L-(+)-酒石酸]，其仅含有Fe(CO)的Δ对映体。使用对映体纯的()-(-)-3-羟基四氢呋喃作为添加剂得到α-(BEDT-TTF)[Fe(草酸盐)].(HO).乙醇.()-(-)-3-羟基四氢呋喃，其包含手性客体且含有Fe(CO)的Λ和Δ对映体的外消旋混合物。对映体纯的()-苯基环氧乙烷水解为外消旋1-苯基乙烷-1,2-二醇，以生成外消旋β"-β"-(BEDT-TTF)(HO/HO)Fe(CO).1-苯基乙烷-1,2-二醇。
