Synthesis and structure of novel closo-dodecaborate-based glycerols
摘要:
The reactions of oxonium derivatives of [B(12)H(12)](2) with different glycerol-based nucleophiles were studied. A series of novel closo-dodecaborate- based glycerols with different net charges on the molecules were prepared. A structure of {2-[2-(4-(2, 3-dihydroxypropyl)-dipiperazinium-1-yl)-ethoxy]-ethoxy}-undecahydro-closo-dodecaborate was determined and the existence of different intermolecular H-bonds was shown.
