Stereocontrol in the synthesis of dinuclear metal complexes of sulfinylcalix[4]arenes 2 has been achieved by the arrangement of sulfinyl functionalities. Thus, the treatment of the(rtct) isomer of 2 (2(rtct)) with an excess of Et(3)B affords syn dinuclear boron complex 4, while a similar treatment of rctt and rcct isomers 2(rctt) and 2(rcct) yields anti dinuclear complexes 5 and 6, respectively.
通过亚磺酰官能团的排列实现了亚磺酰杯[4]芳烃2双核金属配合物合成中的立体控制。因此，用过量的Et(3)B处理2的(rtct)异构体（2(rtct)）可得到顺式双核硼配合物4，而对rctt和rcct异构体2(rctt)和2(rcct)进行类似处理则分别得到反式双核配合物5和6。
