Abstract

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 α, ω-dihalides is facilitated by the presence of gem-dialkylsilyl and gem- dialkylstannyl groups in the precursors. Conformations of several of the new ring systems ...
