Cycloaddition Reactions of Organometal Complexes, I. The Synthesis of Four-membered Metalla-Heterocycles by Cycloaddition of (Isonitrile)cobalt Complexes and Isocyanates or Isothiocyanates

The reaction of C5H5(PMe3)CoCNR (R = Me, Ph) with isocyanates OCNR' (R' = Me, Ph) leads to the metalla-heterocycles (I - 3) in nearly quantitative yields.The analogous four-membered ring compounds (4 - 6) are obtained from C5H5(PMe3)CoCNR (R = Me, Ph, c-C6H11) and SCNMe.In the reaction of C5H5(PMe3)CoCNtBu with SCNMe and of C5H5(PMe3)CoCNMe with SCNtBu the complex (4) is also formed.The X-ray structure analyses of 4 and 5 show the presence of planar four-membered CoCNC rings together with a trigonal-planar coordination of the corresponding C, N and C ring atoms.The protonation and methylation reactions of the metalla-heterocycles 1 - 5 yield diaminocarbene complexes, in most cases by preserving the four-membered CoCNC-ring.The structure of these complexes is discussed on the basis of their IR and NMR data.
