More than 40 new 4- to 12-membered ring heterocycles containing various combinations of Group 14 and 16 elements Si, Sn, S, Se, and Te have been synthesized and fully characterized. Synthesis of these small-ring as well as medium-ring (mesocyclic) heterocycles from alpha,omega-dihalides is facilitated by the presence of gem-dialkylsilyl and gem-dialkylstannyl groups in the precursors.

(Bis‐selenolato) and (bis‐tellurolato)diironcomplexes [2Fe2E(Si)] were prepared and compared with the known (bis‐thiolato)diironcomplex A to assess their ability to produce hydrogen from protons. Treatment of [Fe3(CO)12] with 4,4‐dimethyl‐1,2,4‐diselenasilolane (1) in boiling toluene afforded hexacarbonylμ‐[1,1′‐(dimethylsilylene)bis[methaneselenolato‐κSe : κSe]](2 −)}}diiron(FeFe) (2).
