合成了对映体纯形式的平面手性二茂铁稠合亚胺盐。由该盐成功地合成了新型的平面手性环（氨基）（二茂铁基）卡宾，并用硫和氯化铜进行了卡宾捕获实验。在铜催化的α，β-不饱和酯的不对称β-硼化反应中，初步证明了卡宾作为过渡金属手性配体的实用性.
Planar chiral ferrocene-fused iminium salts were synthesized in enantiomerically pure form. The novel planar chiral cyclic (amino)(ferrocenyl)carbene successfully generated from such salt was subjected to carbene trapping experiments with sulfur and copper chloride. The utility of the carbene as a chiral ligand for transition metals was preliminarily demonstrated in the copper-catalyzed enantioselective β-boration of an α,β-unsaturated ester.
