Darstellung und eigenschaften von substituierten mangan—carbonyl-komplexen mit funktionellen SH-gruppen am liganden

Novel substitution products of bromopentacarbonylmanganese with functional SH groups at the phosphine ligand are obtained by reaction of the phosphine sulphides R₂P(S)H (R = CH₃, C₂H₅, C₆H₅) with BrMn(CO)₅. The presence of SH groups is detected not only chemically by S-methylation with CH₂N₂ but also ¹H NMR, mass and IR spectroscopically.
