Cyclic alkylamino carbenes (CAACs) have become an emerging ligand classes in homogenous catalysis in the last decades. One of the role of these ligands is to stabilize the active form of the catalyst during the catalytic cycle steps (oxidative addition, transmetallation, and reductive elimination). Apparently CAACs’ carbene render better stabilizing effect than phosphine and N-heterocyclic carbene (NHC) ligands. The water-soluble CAAC ligands may provide alternative routes to environmental benign chemical processes. Carrying catalytic reactions in water may reduce the environmental impact and widen the scope of application areas. Water soluble CAAC ligands can be functionalized with quaternary ammonium salt containing groups, resulting in polar compounds rendering high hydrophilic character. The synthesis of new amino group containing CAAC water-soluble ligands will be presented.
