“…It is well known that boroxines are cyclic trimers of organoboronic acids produced by the & Qian-Feng Zhang ahutchang@yahoo.com; zhangqf@ahut.edu.cn dehydration of the acids. Furthermore, arylboroxines have recently found applications in the areas of covalent organic frameworks, nano-scale molecular scaffolds, and non-covalent polymer functionalization [7][8][9][10]. It is noted that triarylboroxines form adducts with Lewis bases e.g.…”

The treatment of phenylboronic acid PhB(OH) 2 with 4,4 0 -bipyridine (4,4 0 -bpy) in a 3:1 ratio afforded adduct [(Ph 3 B 3 O 3 )(g 1 -4,4 0 -bpy)] (1), whereas the reaction of PhB(OH) 2 with 4,4 0 -bpy in a 6:1 ratio afforded adduct [(Ph 3 B 3 O 3 ) 2 (l-4,4 0 -bpy)] (2). Similarly, the reaction of PhB(OH) 2 with trans-1,2-bis(4-pyridyl)ethylene (bpe) in a 6:1 ratio gave bpe bridged adduct [(Ph 3 B 3 O 3 ) 2 (l-bpe)] (3). The crystal structures of 1ÁC 6 H 6 , 2Á2C 7 H 8 , 2ÁC 6 H 14 , and 3ÁC 6 H 6 , along with other spectroscopic properties are reported. The weak NÁÁÁH-C hydrogen-bonds exist in the one-dimensional chains of 1ÁC 6 H 6 . Graphical Abstract Treatment of PhB(OH) 2 with 4,4 0 -bpy or bpe under different conditions afforded three new adducts [(Ph 3 B 3 O 3 )(g 1 -4,4 0 -bpy)] (1), [(Ph 3 B 3 O 3 ) 2 (l-4,4 0 -bpy)] (2) and [(Ph 3 B 3 O 3 ) 2 (l-bpe)] (3) through the B-N dative bonds.

“…These were mainly synthesized by treatment of boronate esters with pyridyl based ligands [10e15]. Molecular cages, for example, have been obtained by condensation of a tetraboronic acid with a dicatechol linker or by condensation of triboronic acids with tetra-ols and hexaols [16].…”
