An original multi-cooperative catalytic approach was developed by combining metal–ligandcooperation and Lewis acidactivation. The [(SCS)Pd]2 complex featuring a non-innocent indenediide-based ligand was found to be a very efficient and versatilecatalyst for the Conia-ene reaction, when associated with Mg(OTf)2. The reaction operates at low catalytic loadings under mild conditions with HFIP as a
