摘要

The dimethyl PdII complex (MeN4) PdIIMe2 (MeN4= N, N′-dimethyl-2, 11-diaza [3, 3](2, 6) pyridinophane) is readily oxidized by dioxygen in the presence of protic solvents to selectively eliminate ethane. UV–vis, EPR, ESI-MS, and NMR studies reveal the formation of several PdIII and PdIV intermediates during the aerobically induced C–C bond formation reaction, including the key intermediate [(κ3-MeN4) PdIVMe3]+, which leads to ethane ...
