摘要：

A new oxidation procedure of alkynes catalyzed by Tp(PPh3)(CH3CN)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(PPh3)(PhCN)Ru-Cl gave rise to the ruthenium metallacycle complexes.
