Thioether containing ligands for asymmetric allylic substitution reactions

This review covers reports in the literature on the use of thioether ligands in Pd-catalysed asymmetric allylic substitution reactions from 1996 to June 2006. In the first section, we will cover the results using (S,S)-homo and (S,S)-heterodonor ligands. In the next section, we will present the results using heterodonor (S,X)-ligands, emphasizing the results obtained with (S,N)- and (S,P)-donor ligands. We also discuss any reported mechanistic aspects according to the allylic substitution results.
