Summary: Synthesis and characterization of new bromocarbonilcomplejos manganese (I) with the ligands bidentados 1,2-bis (difenilfosfinoxi) ethane (dffe) and 1,2-bis (diisopropilfosfinoxi) ethane (dipfe). [MnBr (CO) 3 (dffe)] (1) and [MnBr (CO) 3 (dipfe)] 2 (2). The bromotricarbonilcomplejos MN (R) with ligands bidentados earlier were used as precursors to bromotricarbonilcomplejos of Mn (I) with ligands monodentados: fosfito (P (OR) 3), fosfonito (PPh (OR) 2) and fosfinito (PPh2 ( OR)). [MnBr (CO) 2 (dffe) L]; L = P (Ome) 3 (3), P (OEt) 3 (4), [MnBr (CO) 3L2]; L = PPh (OEt) 2 (5) , PPh2 (OEt) (6). It replaces the ligand bromine of bromotricarbonilcomplejos with ligands dffe and dipfe by reaction of the complex with trifluorometanosulfonato silver and trifluoracetto silver, and are derived compounds [Mn (OSO2CF3) (CO) 3 (Dffe)] (7) and [Mn (OSO2CF3) (CO) 3 (dipfe)] (8). The trifluorometanosulfonatocarbonilcomplejos of Mn (I) with the ligand bidentados 1,2-bis (difenilfosfinoxi) ethane (dffe) and 1,2-bis (diisoproilfosfinoxi) ethane (dipfe) are reacting with acetonitrile, potassium cyanide and potassium thiocyanate to replace linked triflato by new ligands and characterized by the usual techniques, leading to the complex [Mn (CH3CN) (CO) 3 (dffe)] (CF3SO3) (9), [Mn (CH3CN) (CO) 3 ( dipfe)] (CF3SO3) (10), [Mn (SNA) (CO) 3 (dffe)] (11), (SNA) Mn (CO) 3 (dipfe)] (12) [Mn (NC) (CO ) 3 (dipfe)] (13) [Mn (OOCCF3) (dffe)] (14) and [Mn (OOCCF3) (CO) 3 (dffe)] (15) and [MnOOCCF3 (CO) 3 (dipfe)] Synthesis and characters of hidrurocomplejos manganese I with the ligands bidentados 1,2-bis (difenilfosfinoxi) ethane (dffe) 1,2-bis (diisopropilfosfinoxi) ethane (dipfe) and 1,3-bis (difenilfosfinoxi) propane (dffp ) and monodentados fosfito and fosforito, to the new complex [MnH (CO) 3 (dffe)] (16) [MnH (CO) 3 (dipfe)] (17) and [MnH (CO) 3 (dffp) ] (18) [MnH (CO) 2 (dffe) L] (19), L = P (OMe) 3 (19th), P (OEt) 3 (19b), PPh (OMe) 2 (19c), PPh ( OEt) 2 (19d) [MnH (CO) 2 (dipfe) L] (20), L = P (OMe) 3 (20th), P (OEt) 3 (20b), PPh (OMe) 2 (20c) PPh (OEt) 2 (20d). We reactions protonación of hidrurocarbonilcomplejos of Mn (I) earlier HBF4.Me2O to obtain hidrógenos complex.
