摘要: Abstract The substitution compounds Br(OC) 4 MPPh 2 (CH ) n Cl (M = Mn, Re; 5, 6) are obtained by the action of (5-chloropentyl- and 6-chlorohexyl)diphenylphosphanes Cl(CH PPh , which formed from α,ω-dihalogenoalkanes NaPPh on manganese rhenium complexes BrM(CO) 5 in cyclohexane. If they subjected to reductive cycloelimination with sodium amalgam THF only seven-membered mangana- rhenacycloheptanes (OC) (C H can be isolated satisfactory yields. They crystallize triclinic space group P 1 Z . influence ring size heterocycles 1–5) bonding parameters reactivity MC σ bond is investigated. Insertion CO into MnC SO ReC affords cyclic acyl sulfinato MnPPh C O RePPh CH S respectively.
