Polycationic ligands in gold catalysis: synthesis and applications of extremely π-acidic catalysts.

Abstract

Very often ligands are anionic or neutral species. Cationic ones are rare, and, when used, the positively charged groups are normally appended to the periphery of the ligand. Here, we describe a dicationic phosphine with no spacer between the phosphorus atom and the two positively charged groups. This structural feature makes its donor ability poorer than… (More)
