    • Boronic acids 21a-c, like their precursors 4a,b coexist with anhydride forms of boronic acids with different degree of oligomerization. The NMR spectra of 21a-c derivatives purified by crystallization were rather complicated. On the other hand, when compounds 21a-c were isolated by column chromatography on silica gel, the NMR spectra of these products became almost fine due to the cleavage of the ether bonds in the associates.
