Selenium(IV)-dichlorides , readily available by treatment of methyl ketones with phenylselenium trichloride or selenium tetrachloride, were treated in methylene chloride with pyridine to give α-chloroselenides in a Pummerer-like reaction. Sulfurylchloridechlorination of these materials and repeated pyridine treatment similarly afforded α,α-dichloroselenides .
