1-benzoxazines via formation of tetrafluoroborates. The substitution of halogen in 2-(α-haloalkyl)-4,4-diphenyl-4H-3,1-benzoxazines by NH and SH nucleophiles was performed. The effect of electrophilic substitution in the annelated aromatic ring in a series of 2,4-substituted 4H-3,1-benzoxazines has been studied.
已经开发出一种通过形成四氟硼酸酯来制备取代的4 H -3,1-苯并恶嗪的新方法。进行了NH和SH亲核试剂取代2-(α-卤代烷基)-4,4-二苯基-4 H -3,1-苯并恶嗪中的卤素。已经研究了一系列2,4-取代的4 H -3,1-苯并恶嗪中的芳族芳环中亲电取代的影响。
