N)(p-cymene) 3a-3d via ortho C–H activation/deprotonation by acetate. The presence of the stable Ru–Cl bond rather than a labile Ru–OAc bond is crucial for the isolation of the complexes. This preparative method of cyclometallates was applied to 2-phenyloxazoline, and benzo[h]quinoline and to the improved synthesis of 2-phenylpyridine and 1-phenylpyrazole derivatives. The molecular structures of three cycloruthenates
芳烃与[RuCl 2(对-cymene)] 2和4当量的反应。的KOAc在甲醇引线到N-孺-C的形成室温下的cycloruthenates的RuCl(arylimine- ķ C,N)(p -cymene)3A-3D通过邻位C-H活化/去质子化由酯。稳定的Ru–Cl键而不是不稳定的Ru–OAc键的存在对于复合物的分离至关重要。这种环金属酸盐的制备方法应用于2-苯基恶唑啉和苯并[ h ]喹啉,以及用于改进的2-苯基吡啶和1-苯基吡唑衍生物的合成。报道了三种环钌酸酯的分子结构。
