摘要：
Dithiolated derivatives of 1,2-dicarba-closo-dodecaboranes are common ligands to be used for self-assembling monolayers, nanoparticles or transition complexes due to their robust molecular structure. The 9,12-dimercapto-1,2-dicarba-closo-dodecaborane, a derivative with two SH-groups in adjacent positions, is an interesting unit for the preparation of derivatives additionally functionalized in positions one and two. In this contribution, we report a convenient synthesis of 1,2-disubstituted 9,12-dimercapto-1,2-dicarba-closo-dodecaboranes starting from the 9,12-dimercapto-1,2-dicarba-closo-dodecaboranes with SH groups protected using methoxy-methyl (MOM) groups. All compounds are well characterized via HiRes-mass spectroscopy, H-1, C-13 and B-11 NMR-spectroscopy and IR spectroscopy. The precursor 9,12-bis(methoxy-methylthio)-1,2-dicarba-closo-dodecaborane was additionally characterized with X-ray-structural analysis. (C) 2012 Elsevier Ltd. All rights reserved.
