Abstract
The cover picture shows a novel route for synthesis of 3-SH-1,2-dicarba-closo-dodecaborane. The reaction proceeds through Pd-catalyzed iodine exchange with the sulfur nucleophile TIPS–SH in ortho-carborane. The presented method makes available the previously inaccessible mono- and di-B-mercaptocarboranes from iodocarboranes. The thiolated borane clusters can be applied in thiol-based self-assembled monolayers (SAMs) on surfaces such as gold. The properties of the SAMs can be finely tuned by the choice of the carborane isomer and the position of the mercapto substituent. Details are discussed in the Short Communication by M. F. Hawthorne et al. on p. 2488 ff. For more on the story behind the cover research, see the Cover Profile.
