triethylamine–borane and in those which involve heating the 1 : 1 adduct of the arylamine and trichloroborane. Products isolated in these cases include diazaboranes (bisaminoboranes)[(ArNH)2BH], aminodichloroboranes [ArNHBCl2], and triazaboranes (boronamines)[ArNH·BX·NAr·BX·NArH](X = Cl or H). A possible reaction path to the formation of borazines involving these intermediates is discussed.
已经在形成1,3,5-三芳基-和2,4,6-三
氯-1,3,5-三芳基-
硼嗪的途径中研究了邻位取代的作用。在涉及加热芳基胺和
三乙胺-
硼烷的混合物的反应中以及在加热涉及芳基胺和三
氯硼烷的1:1加合物的反应中,在邻位存在两个取代基均会抑制等效
硼嗪的形成。在这些情况下分离出的产物包括二氮杂

氨基二
氯硼烷[ArNHBCl 2 ]和三氮杂
硼烷(
