已成功开发出一种有效的多相钯-多金属氧酸盐钯-H 6 PV 3 Mo 9 O 40 / C催化剂,用于通过碳-氢(CH)活化和碳-氮(CN)形成碳-碳(CC)键通过使用氧作为末端氧化剂的氧化胺化形成键。偶联过程很简单,并且使用相对温和的条件来形成所需的产物。此外,由于不需要其他试剂(例如有机/无机氧化剂),因此产生的废物更少,并且水是唯一产生的副产物。
The silylcupration of N-phenyl-N-ethynyl-aniline, occurs regioselectively leading to silylation at the β-carbonatom. Subsequent reaction of the resulting vinyl copper adduct with electrophiles, opens a new flexible route to functionalized enamines.

An efficient heterogeneous palladium-polyoxometalate catalyst with the formula Pd-H6PV3Mo9O40/C has been successfully developed for carbon-carbon (CC) bond formation via carbon-hydrogen (CH) activation and carbon-nitrogen (CN) bond formation viaoxidative amination using oxygen as the terminal oxidant. The coupling processes are simple, and use relatively mild conditions to form the desired products
