Treatment of the diborane(4) compound B2(NMe2)4 with aniline or 2,6-dimethylaniline results in the primary amido compounds B2(NHR)4
(R = Ph, 2,6-Me2C6H3); subsequent treatment with n-BuLi in toluene in each case affords the first examples of anionic imidodiborates namely Li4(thf)6B2(NPh)4 and Li4(thf)4B2(N-2,6-Me2C6H3)4; all complexes have been characterised crystallographically.
用
苯胺或
2,6-二甲基苯胺处理二
硼烷(4)化合物 B2(NMe2)4,可得到伯
氨基化合物 B2(NHR)4(R = Ph,2,6-Me2C6H3);随后,在每种情况下都用正
叔丁基锂在
甲苯中进行处理,得到了首例阴离子
酰亚胺二
硼酸盐,即 Li4(thf)6B2(NPh)4 和 Li4(thf)4B2(N-2,6-Me2C6H3)4 ;所有复合物都已进行了晶体学表征。
