已经发现，1H-2，1-苯并氮杂硼杂环戊烯可以通过取代的苄基氨基氯硼烷与Al_2Cl_6在CH_2Cl_2中在0 ℃下的相互作用来制备，所获得的C-13 NMR光谱数据有利于亲电取代机理，该机理涉及阳离子络合物作为反应中间体的形成。
It has been found that 1H-2,1-benzazaboroles can be prepared by the interaction of substituted benzylaminochloroboranes with Al2Cl6 in CH2Cl2 at 0 degrees C, the C-13 NMR spectroscopy data obtained being in favour of an electrophilic substitution mechanism involving formation of cationic complexes as reactive intermediates.
