Abstract: Recent chemistry of four-membered ring selenium compounds is reviewed followed by a summary of work in our laboratories in this area. 2-Thia-6-selenaspiro[3.3]heptane has been synthesized for the first time. X-ray structures for the latter compound as well as for 2,6-dithiaspiro[3.3]heptane and 2,6-diselenaspiro[3.3]heptane have been determined. These compounds are useful as "rigid-rod" ligands for coordination to transition-metal complexes.
Keywords: Selenium; four-membered rings; X-ray structures; metal complexes; selenetane.
