Nucleophillc Aromatic Substitution Reactions of 1,2-Dihydro-1,2-Azaborine

摘要

1,2-Dihydro-1,2-azaborine (1) is a benzene isostere in which a C=C unit of benzene is replaced with an isoelectronic B-N unit. As part of our program to develop the basic scienceand applications of 1,2-azaborine heterocycles, we have focused on expanding the scope of synthetically accessible 1,2-azaborines and investigating the aromatic character of this family of heterocycles.
