It was proposed that Martin’s reaction follows a classical cross-coupling mechanism, as rational explanation for the products obtained. Cross-coupling reactions are processes in which two reactants, usually holding an activating group, react together with the aid of a metal catalyst. \cite{Zapf_2005} This mechanism comprises three elementary steps as shown in Figure \ref{317534}: oxidative addition, in which one of the reactants react with the metal atom, which undergoes a formal 2-electron oxidation; transmetalation, where the second reactant exchanges with the activating group and adds itself to the catalyst; and finally in the reductive elimination the product is formed, and the catalyst recovered. Thus, the cross-coupling mechanism consists in the exchange of two fragments (X and Y in Figure  \ref{317534}) between two different reactants (R-X and R’-Y) assisted by a metal complex ML2 as catalyst.
