1,4-Dihydro-1,1-dimethyl-1-stannanaphthalene (10) has been prepared by a multistep synthesis starting from α,2-dibromotoluene (6). The reaction of 10 with MeBBr2 followed by LDA afforded lithium 1-methyl-1-boratanaphthalene (2a). The reaction of 10 with BCl3, followed by diisopropylamine and subsequent treatment with LDA, gave lithium N,N-diisopropyl-1-amino-1-boratanaphthalene (2c). The boratanaphthalenes
1,4-二氢-1,1-二甲基-1- stannanaphthalene(10)已准备由多步合成从α开始,2-二溴甲苯(6)。10与MeBBr 2的反应,然后与LDA进行反应,得到1-甲基-1-硼萘甲酸锂(2a)。10与BCl 3的反应,然后与二异丙胺反应,再用LDA处理,得到N,N - N-二异丙基-1-氨基-1-硼萘基锂(2c)。使用1 H NMR,11 B NMR和13 C NMR光谱对硼烷萘进行了表征。在P ķ2c的共轭酸中的α接近于茚。图2a与混合[Cp *的RuCl]进行反应4,以形成钌夹心化合物4a中,其中,所述boratanaphthalene是η 6结合到茹。2c与Cp * ZrCl 3反应形成Cp * ZrCl 2加合物5c,其中硼烷萘单元不对称地结合到Zr上。
