Boron–Nitrogen Adducts of 1,3,5‐Triaza‐7‐phosphaadamantane (PTA): Synthesis, Reactivity, and Molecular Structure

“…The polymeric structure is obtained through formation of a Lewis acid-base adduct from one nitrogen atom on each PTA to a boron atom of triphenylboroxin. Two of the three boron atoms in triphenylboroxin form N-B bonds, which affords a linear polymer, with the geometry about the coordinated boron sites significantly distorted [ [28][29][30] Comparison of the structure of 3 with the parent complex CpRu(PTA) 2 Cl and the diprotonated form [CpRu(PTAH) 2 Cl] 2+ , previously reported by us, [3,4] reveals that the core organometallic portion of 3 is largely unchanged, Table 6. The P-Ru-P angle is slightly less obtuse and the Ru-P bond lengths are elongated slightly (Ϸ 0.01 Å) in 3 vs. the other two complexes.…”

Dynamic Iminoboronate‐Based Boroxine Chemistry for the Design of Ambient Humidity‐Sensitive Self‐Healing Polymers

“…[27,28] Although simple imines are very sensitivet ow ater owing to the hydrolysis reaction, it has been shownt hat the dative bond within iminoboronate species makest he imine product more robust against hydrolysis due to an enhanced thermodynamic stability. [30][31][32] Therefore, we planned to use the iminoboronate linkaget od esign the boroxine-based dynamic crosslinked network andw ee xpected that the boroxine BÀOb onds would conserve their dynamic feature even though Lewis acid-base interactions involve boron atoms and could consequently disrupt the reversion process. Furthermore, the construction of such iminoboronate adducts from boronic acid and amine moieties remains relatively simple and straightforward under mild conditions.…”

Efficient Preparation of 2-Aminomethylbiphenyls via Suzuki-Miyaura Reactions

“…20,21,24,25 Toyota et al reported the presence of N-B coordination bond in the boronic ester derivative of 2 and showed that the dissociation of the dative bond proceed by a S N 2-type mechanism. 26 A sp 2 trigonal, uncoordinated boron NMR signal and a tetragonal sp 3 -coordinated signal with an amine are approximately d = 30 and 15 ppm, respectively.…”

“…However, analogous trimerized cyclic boronic anhydride is a structural motif often found for boronic acids. [20][21][22] In the cyclic form of 1, the boron atom is tetrahedral and coordinated with the nitrogen to form a dative bond. The N-B bond length is about 1.75 Å in the boronic acid and in two of the three N-B interactions.…”
