Reduction of C,N-chelated chloroborane [2-(CHNtBu)C6H4]BPhCl (1) with the potassium metal afforded (3,3′)-bis(1-Ph-2-tBu-1H-2,1-benzazaborole) (2). Compound 2 is formed via C–C reductive coupling reaction. Subsequent reduction of 2 with two equivalents of the potassium metal produced orange crystals of 1Ph-2tBu-1H-2,1-benzazaborolyl (Bab) potassium salt K(THF)(Bab) (3). Compound 3 is able to react
用钾金属还原C,N螯合的氯硼烷[2-(CH N t Bu)C 6 H 4 ] BPhCl(1)得到(3,3')-bis(1-Ph-2- t Bu-1 H -2,1-苯并氮杂硼烷)(2)。化合物2是通过C–C还原偶联反应形成的。随后用两当量的钾金属还原2,得到1Ph-2 t Bu-1 H -2,1-苯并氮杂硼烯丙基(Bab)钾盐K(THF)(Bab)的橙色晶体(3)。化合物3能够与简单的亲电试剂(MeI或Me 3 SiCl)反应,从而形成取代的1 H -2,1-苯并氮杂硼烷。
