tetraphenylcyclopentadiene (7) and the classical “tetracyclone route” are tested as preparative entries to a variety of pentaarylcyclopentadienes 4 monofunctionalized in the ortho-position. The corresponding chelated ruthenium complexes 6 can be formed either thermally induced or by photochemical irradiation. These complexes contain stereogenic ruthenium centers. Enantiopure complexes 6f and 6g, with chiral oxazoline
测试了Pd催化的四苯基环戊二烯(7)的芳基化反应和经典的“四旋风途径”作为在邻位单官能化的各种五芳基环戊二烯4的制备入口。相应的螯合钌配合物6可以通过热诱导或通过光化学辐射形成。这些复合物含有立体构型的钌中心。对映体纯的配合物6f和6g,带有手性恶唑啉基团,用于苯基酮9的不对称转移氢化反应。
