Abstract

Abstract: Metalation of secondary phosphanes HP RR ′ [ R = R ′ = C6 H4 ‐4‐Me, C6 H3 ‐3, 5‐Me2 (3 ), C6 H4 ‐4‐NMe2 (4 ); R / R ′ = Ph/ c Hex] with Mn2 (CO)10 in boiling xylene (mixture of isomers), until the evolution of gaseous carbon monoxide ceases, leads to the formation of the dinuclear complexes of the type [(OC)4 Mn(μ‐P RR ′)]2 [ R = R ′ = C6 H4 ‐4‐Me (5 ), C6 H3 ‐3, 5‐Me2 (6 ), R / R ′ = Ph/ c Hex (7 ), R = R ′ = C6 H4 ‐4‐NMe2 (8 )] with poor to moderate yields. These manganese(I) complexes are only sparingly soluble or even nearly insoluble in hydrocarbons at room temperature. Planar four‐membered Mn2 P2 rings represent the central moiety with four carbonyl ligands at each manganese(I) atom. The steric demand of the P‐bound substituents influences the Mn–P bond lengths as well as the P–Mn–P bond angles. Abstract :
