Popis výsledku v původním jazyce

The reaction between excess n-C4H9ONO and arachno-4,5-C2B7H13 (1) in diethyl ether at room temperature results in the formation of the first representatives of the arachno ten-vertex azadicarbaborane family, arachno-6,5,9-NC2B7H12 (2) and arachno-6,5,10-NC2B7H12 (3) in yields of 6 and 20%, respectively. The reaction also generates exo-8-CH3-hypho-7,8-NCB6H11 (4) (yield 5%) as a result of the extrusion of the CH2 group from the cluster of the starting dicarbaborane to generate a terminal methyl unit. Thereaction between 8,9-mu-NH2-arachno-5,6-C2B8H11 (5) and NaH, followed by treatment with iodine and water, produced the unique endo isomer of 4, endo-8-CH3- hypho-7,8-NCB6H11 (6) (yield 22%). The reaction between n-C4H9ONO and nido-5,6-C2B8H12 (7) in hexane at reflux generates the first compound of the ten-vertex nido azadicarbaborane family, nido-6,8,9-C2NB7H10 (8), in 13% yield. The structures of all the compounds isolated are proposed on the basis of NMR spectroscopy, the geometries o
