The 13 C, 29 Si and 119 Sn chemical shifts of 2‐ and 2,5‐substituted organometallic (M=C, Si, Ge, Sn, Pb) derivatives of furan were measured. The most important factors, determining the specific features of the studied spectra, are d‐orbital availability and atomic radius of the central atom M, as well as the relatively higher (as compared with benzene) energies of the π‐electron energy levels of the furan ring.
