Paragraph 0086, (2021/12/29)
Disclosed is a fluorescent compound as represented by general formula I, or a salt, an enantiomer, a diastereomer, a tautomer, a solvate or a polymorph thereof, having the structure (I); wherein m and n are each an integer between 0-10; and Y1 and Y2 are each independently selected from the group of hydrogen, phenyl, hydroxyl, carboxyl, an ester group, a boric acid group, a borate group, and a 3 to 7 membered ring substituted with one or more boric acid groups or borate groups, and at least one of Y1 and Y2 is a boron-containing group. The compound has the characteristics of a high fluorescence intensity and a high sensitivity.

Owing to the unusual reactivity of dialkylamine-borane complexes, a methodology was developed to simply access boronic acids. The intrinsic instability of magnesium aminoborohydride was tweaked into a tandem dehydrogenation borylation sequence. Proceeding via an autocatalytic cycle, amineborane dehydrogenation was induced by a variety of Grignard reagents. Overall, addition of the organomagnesium species onto specially designed dialkylamine-borane complexes led to a variety of boronic acids in high yields. In addition, the reaction can be performed under Barbier conditions, on a large scale.
