A series of 2-(picolyl)borane molecules were synthesized as products of the reaction between 2-(picolyl)lithium and R2BOMe (R = ethyl, 9-BBN, phenyl, 9-borafluorenyl). The 2-(picolyl)boranes were dimeric; whereas, monomers coordinated to LiOMe could be isolated when the synthesis was carried out in the presence of TMEDA and THF. The 2-(picolyl)boranes undergo reaction with nitriles, ketones, aldehydes
multi‐functionalized molecular systems with a potential as a supramolecular building block. Furthermore, the conjugated structure of the cyclicboron‐amidine compounds can be changed upon alkylation of the boron atom that increases the coordination number of boron. The combination of Lewis acid (borane) and conjugated base (amidine) provides rich structural diversity of heteroatom‐containing π‐conjugated

for the oxidation of 2-furancarboxylic acid, oxidative coupling of benzylamines and oxidation of sulfides. Among the studied compounds, the diarylborinic derivative bearing a 5-chloro-8-oxy-7-iodoquinolinate ligand was selected as the most economic singlet oxygen sensitizer. However, the diphenylborinic complex bearing an 8-oxyquinolinate ligand was the most efficient for the selective oxidation of various
在这项工作中,开发了一种合成方案,以获得一系列带有二芳基硼部分的二芳基硼络合物,该二芳基硼部分与衍生自5-氯-8-羟基-7-碘喹啉、喹啉-2,4-二羧酸的各种二齿N,O-配体螯合或2-(2-羟基-5-甲基苯基)苯并三唑。通过 NMR、IR、CV、UV-vis 和单晶 X 射线衍射分析对所得配合物进行了表征。实验数据得到了理论计算的支持。所获得的配合物作为单线态氧敏化剂用于2-呋喃甲酸的氧化、苄胺的氧化偶联和硫化物的氧化进行测试。在所研究的化合物中,带有5-氯-8-氧基-7-碘喹啉配体的二芳基硼衍生物被选为最经济的单线态氧敏化剂。然而,带有8-羟基喹啉配体的二苯基硼配合物对于将各种苯甲胺选择性氧化为其各自的N-亚苄基苯甲胺来说是最有效的。
