A method for forming bridged biaryl compounds via the intramolecular oxidative biarylic coupling of precursor compounds containing two aromatic rings linked via a hydrocarbon chain is disclosed along with the ruthenium catalyst for its implementation and new compounds resulting therefrom. The biarylic coupling method is characterized in that the biarylic precursors are cyclized in the presence of the catalyst tetrakis(trifluoroacetate) of ruthenium (IV).
本发明揭示了一种通过前体化合物中含有通过碳氢链连接的两个芳环的内分子氧化双芳基偶联形成桥式双芳基化合物的方法,以及用于实施该方法的
钌催化剂和由此产生的新化合物。该双芳基偶联方法的特点在于,在
钌(IV)的
三氟乙酸盐催化剂存在下,双芳基前体分子被环化。
