• While P( v ) 1,2-oxaphosphetanes were investigated in great detail over the past decades, the knowledge about P( v ) 1,2-thiaphosphetanes is rather scarce, and P( iii ) derivatives are unknown. Herein, we present the synthesis of the first P( iii ) complex derivatives formed in the coordination sphere of group 6 metals and, additionally, the first unligated P( iii ) 1,2-thiaphosphetanes. The latter display an unusually low HOMO-LUMO gap thus constituting excellent candidates for redox-cycling organocatalysts. The 1,2-thiaphosphetane heterocycle could be synthesized for the first time in the coordination sphere of a metal complex ( I ) from which the free ligand ( II ) could be obtained, too.
