Pentacarbonyl(thiobenzaldehyde)tungsten (1) reacts with phosphanes PR3 to give the phosphoniothiolate complexes (CO)5W (2) (R = Me, Et, Ph, 4-MeC6H4).Similarly, the thiobenzophenone complex (CO)5W (3) affords (CO)5W (4).The phosphoniothiolate complexes obtained from 1 and PPh2H or P(2,4,6-Me3C6H2)H2 rapidly rearrange by formal S,P migration of (CO)5W and P,C migration of H to form the phosphate complexes (CO)5W> (5) and (CO)5W> (6/6'). Key Words: Phosphoniothiolate ligands / Thioaldehyde ligands / Rearrangement reaction / Tungsten complexes
