Abstract
A new oxidation procedure of alkynes catalyzed by Tp(PPh(3))(CH(3)CN)Ru-Cl is presented, which provides an efficient way to obtain alkenyl 1,2-diketones via ruthenium alkenyl 1,2-diketone intermediates. In contrast, the analogous reactions with Tp(PPh(3))(PhCN)Ru-Cl gave rise to the ruthenium metallacycle complexes.
摘要
呈现了一种由 Tp(PPh(3))(CH(3)CN)Ru-Cl 催化的炔烃的新氧化方法，该方法提供了一种通过钌烯基 1,2-二酮中间体有效获得烯基 1,2-二酮的方法。相比之下，用 Tp(PPh(3))(PhCN)Ru-Cl 进行类似的反应会生成钌金属环络合物。
