The coordination behaviour of sulfinylimides RNSO (R = SiMe3, Ph) towards CpMn(CO)(3) (Cp = C5H5, C5H4CH3) has been studied. Under total exclusion of water the substitution products CpMn(CO)(2)S(O)NR} (2a,b, 2a',b) with mu (1)-S-linkage are formed. In the presence of water, however, the SO2 complexes 3, 3' as iminofree hydrolysis products are obtained. There are only spectroscopic indications for the directed hydrolytic conversion of the silyl derivatives 2a, 2a' into the unstable HNSO complexes 4, 4' by cleavage of the Si-N-bond and retention of the cumulene moiety. The molecular structures of -piC5H5Mn(CO)(2)-S(O)NSiMe3} (2a) and pi -C5H4CH3Mn(CO)(2) (3') were elucidated by single crystal X-ray analyses.
