Orthomanganated arenes in synthesis VII. Transition‐metal mediated formation of a PP bond; the X‐ray crystal structure of Mn2(μ‐η1, η1‐Ph2PPPh2)(μ‐Cl)2(CO)6

Abstract

AbstractThe reaction of PPh2Cl with orthomanganated acetophenone, 2′‐CH3C(O)C6H4Mn(CO)4, gives Mn2(μ‐η1,η1‐Ph2PPPh2)(μ‐Cl)2(CO)6. An X‐ray structure determination [triclinic, space group P1, a = 10.908(4) Å, b = 11.756(3) Å, c = 12.186(3) Å, α = 96.20(2)°, β = 99.51(2)°, γ = 96.52(2)°] shows two Mn(CO)3 groups held together by two bridging Cl ligands, and further bridged by a Ph2PPPh2 group prepared in situ.
