Cationic nido-Tricarbollide μ-10,11-H-10,11-H2-7-Me3N-nido-7,8,9-C3B8H8+ and Its Halogenated Derivatives: The Slow Iodination Process Occurring through Cationic Iodonium Tricarbollides

Popis výsledku v původním jazyce

A series of nido-tricarbollides based on 10,11-X2-7-Me3N-nido-7,8,9-C3B8H8 (X = H, Cl, Br, I) and their protonated, i.e. cationic, counterparts, which have an extra H-bridge over the B10-B11 vector in the nido open pentagonal belt, were prepared. Their structures have been verified by the joint ab initio (DFT)/GIAO(ZORA)/NMR approach, MS and HR-MS spectroscopy, and X-ray diffraction techniques. The iodination process is quite slow and could be monitored by 11B NMR spectroscopy in conjunction with a computational search for the corresponding reaction pathway. These efforts have revealed the existence of monoiodo nido tricarbollide cationic motifs with an iodine atom in the positions that have features of an asymmetrical bridge over B10(H)-B11(H) in 10,11-H2-7-Me3N-nido-7,8,9-C3B8H8 or B10(I)-B11(H) in 10,11-I,H-7-Me3N-nido-7,8,9-C3B8H8. Interestingly, 1,2-(COOH)2-closo-1,2-C2B10H10 is one of the active acids, which confirms the earlier observation that a dicarboxylic acid based on o-carborane acts as a superacid.
