[closo-B10H8-1,10-(COOH)2]2−: a building block for functional materials?†
[closo-B10H8-1,10-(COOH)2]2− was obtained in five steps and 40% overall yield from [closo-B10H10]2−. It can be converted to [closo-B10H8-1,10-(CO)2] and subsequently to carbonium ylides [closo-B10H8-1-COOH-10-(C(NRCH2)2)]. The diacid, its derivatives, and di-ylide [closo-B10H8-1,10-(C(NHMe)2)2] are characterized by spectroscopic and single crystal XRD methods augmented with DFT results.
