✦ Synopsis

The reactions of q5-CsHs Fe(CO)2 CH,GCR (R = CH3, C&, and CH,Fe(CO)2($-CsHs)), $-C,Hs-Mo(CO), CH, CXC, H5, and Mn(CO)s CH, CWC, H5 ( [M] CH, ECR) with the ketenes (C6Hsjz C=C=O and (t-C4H9)(CN)C=CL-0 and with the N-sulfinyl compounds C, Hs N=S=O and p-CH3 C6H4S0, N= S=O result in the formation of (3 + 2) cvcloadducts _ , _ of the reactants. The respective products of these the basis of infrared, 'H NMR, and 13C NMR spectroscopic data. No reactions were observed between 17' -C, H5 Fe{ CO), CH, ECCH, and C, H5 0, -CN=NC02C,H5 and between $-C5H5Fe(CO)zR (R = CH, and CHz C,H, 0CH3 -p) and the two ketenes.
