Abstract:
Chelate complexes of the type (CO)4MiX2 (X = Me, Cl) have been prepared from NaMn(CO)5] and HMn (CO)5, respectively, by two-step reactions with the ligands Me2PCH2CH2SiX2R′ using alkali salt, amine or HCl elimination. (CO)4MiCl2 is also obtained by cleavage of Mn2(CO)10 with Me2PCH2CH2SiCl3. IN the case of HMn (CO)5 the intermediates (CO)4Mn (H) L L = Me2PSiMe3, Me2PCH2CH2SiMe2 (NMe2), Me2PCH2CH2SiCl2 (NMe2] can be isolated. The new compounds were identified by analytical and spectroscopic (IR, PMR, MS) methods.
