Boron heterocycles azaborines

The electronic similarity suggests that unsaturated boron heterocycles and aromatic systems have 7r-electron transitions in common. In fact, such similarities are abundant, and are one main reason for the statement that certain boron heterocycles possess aromatic properties. The UV spectrum of 5,6-dihydrodibenz[c,e][l,2]azaborine (15) is reminiscent... 

Since the time of the aforementioned reviews, more recent advances in the chemistry of boron therapeutics have been covered by others (2009MI1275). Advances in the chemistry of azaborines have been reviewed recently (2012AG(I)6074), as have those in the medicinal chemistry of boronic acid derivatives, 1,2-azaborines, and icosahedral boranes (carboranes) (2013AJC1118). Advances in the chemistry of tetrahedraUy coordinated B-heterocycles have been reviewed (2000CCR85), and advances in luminescent dyes containing tetrahedral boron centers...
