The 11 H NMR spectrum of B 11 H 14 - clearly shows proton signals（δ,ppm）for exoterminal hydro- gens（0.5～2.5,b,m,11H）and bridged and endo hydrgens（-3.0,b,3H）.The signals at-3.0 ppm disappear on deuteration with D 2 O. The 11 B NMR of B 11 H 14 - shows three kinds of boron signals（a,b and c）.After decoupling b and c merge to b’ and this spectrum appears two resonances:a’(+15.092 ppm,J BH =134.6 Hz, 1B)and b’(+17.125ppm,J BH at 112.4～156.2 Hz,10B). 硼化合物 有机铁化合物 十四氢十一硼烷阴离子 11B NMR boron compound organoiron compounds tetradecahydroundecaborate boron-11 NMR spectrum O627.81;O627.31 中国科学院自然科学基金 1992-04-01 2021-04-01 4
