Conjugation is an important reaction that enables coupling of molecules. Many protocols exist for the synthesis of binary conjugates from two different molecules or for the polyvalent display of a single molecule. There aren't many methods for the synthesis of ternary conjugates. However, methods for ternary conjugation are important for understanding the interplay of interactions between three biomolecules (or any three molecules per se). A strategy for ternary bioconjugation using inverse electron demand Diels–Alder reaction with tetrazine is studied. Ternary conjugation was demonstrated by the reaction of a model glyco-peptide binary conjugate with a fluorescent tagged olefin.

The hydrolytic stability of heteroaryltrifluoroborates under physiological conditions has been analyzed by 19F NMR spectroscopy and is found to be greatly enhanced by the presence of endocyclic ring nitrogens. Stability is further enhanced by the presence of exocyclic electron withdrawing substituents. As with aryltrifluoroborates, NMR analysis suggests that the hydrolysis proceeds via single rate-determining
杂芳基三氟硼酸酯在生理条件下的水解稳定性已通过19 F NMR光谱分析,发现由于存在环内环氮而大大提高。环外吸电子取代基的存在进一步提高了稳定性。与芳基三氟硼酸酯一样,NMR分析表明水解反应通过单个速率确定步骤进行,反映了第一个氟原子的损失。这些络合物的稳定性在金属催化的交叉偶联反应以及产生基于硼酸的18 F-PET显像剂方面均具有重要意义。

redox‐active materials as alternative electrodes for secondarybatteries are emerging. However, reported organic electrode materials are still limited to a few kinds of organic redox groups. Therefore, the development of new redox‐active groups for high‐performance electrode materials is indispensable. Here, we evaluate s‐tetrazine derivatives as a new electrode material in Li‐ion batteries and study
