conditions were compatible with various functional groups on the nucleophiles. Severe limitations were observed when the allylic position of the enyne is substituted by electron-withdrawing groups. The mechanism of the reaction was investigated via the synthesis of a deuterated aromatic ring: we showed that the source of proton involved in the protodemetallation step originates from the acidic activated
