The intermolecular hydroamination of alkynes proceeds very smoothly in the presence of a catalytic amount of the aquapalladium complex [Pd(dppe)(H2O)2](TfO)2. This reaction most probably proceeds through the formation of an equilibrium between the hydroxopalladium and the amidopalladium complexes, and subsequent aminopalladation of alkynes.

在催化量的水钯配合物 [Pd(dppe)(H2O)2](TfO)2 存在下,炔烃的分子间加氢胺化反应非常顺利。该反应最有可能通过在羟基钯和酰胺钯配合物之间形成平衡以及随后炔烃的氨基钯化来进行。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
