Reaction of cyanamide and their derivatives with (η5-C5H5)Mn(CO)3 and (η5-C5H4CH3)Mn(CO)3

The reaction of cyanamide and its derivatives with the (η5-C5H5)Mn(CO)2(THF) and (η5-C5H4CH3)Mn(CO)2(THF) complexes affords the cyanamide substituted complexes of types (η5-C5H5)Mn(CO)2(NCN(R′)(R″)) (2a–d) and (η5-C5H4CH3)Mn(CO)2(NCN(R′)(R″)) (3a–e). All complexes were characterized by spectroscopy (1H, 13C NMR, IR), elemental and mass spectroscopy analysis. Complex 2b (η5-C5H5)Mn(CO)2(NCN(CH3)2) was additionally examined by single crystal X-ray structure determination.
