Metal-Containing Heterocycles: Preparation, Properties, Reactions, LXVII. - Stereochemical Impacts on the Transition of Monomeric Thiophosphinito Manganese Compounds to the Dimeric Complexes The η2-thiophosphinito manganese complexes (3d, e) and the dimeric complexes (4a-c, f) are obtained from BrMn(CO)5 (1) and the secondary phosphane sulfides R2P(S)H (2a-f) [R = Me (a), Et (b), n-Pr (c), i-Pr (d), Cy (e), Ph (f)] in the presence of the auxiliary base Et(i-Pr)2N with elimination of CO. For the kinetic stabilization of 3d, e sterically demanding substituents R at the phosphorus are suitable. The Mn—S bond in 3e is easily cleaved under CO pressure (100 bar) resulting in the formation of (5e). The reaction 3e ⇆ 5e is reversible.
