Novel silylated hydroborate clusters comprising the closo-decaborate cage were prepared and characterized by ¹H, 13C, 11B, 29Si NMR and mass spectroscopy ESI. The synthesis of such silylated clusters was achieved using reactive derivatives of [B10H10]2-, [1-B10H9N2]- and [2-B10H9CO]-. These silylated decaborate clusters constitute a new class of precursors that can be covalently anchored onto various silica supports without any prior surface modification. As a proof of concept, the synthesized precursors were successfully anchored on mesoporous silica, SBA-15 type, in different percentages, where the mesoporous material retained its structure. All materials modified with closo-decaborate were characterized by 11B and 29Si solid state NMR, XRD, TEM and nitrogen sorption. [ABSTRACT FROM AUTHOR] |
