Selenium(IV)-dichlorides 1, readily available by treatment of methyl ketones with phenylselenium trichloride or selenium tetrachloride, were treated in methylene chloride with pyridine to give α-chloroselenides 2 in a Pummerer-like reaction.Sulfuryl chlor

PREPARATION OF 2,5-DIACYLSELENOPHENES BY CONDENSATION 0F α,α'-DIKETOSELENIDES WITH GLYOXAL

The reaction of selenium oxychloride with 2 equiv. of ketones affords α,α'-diketo selenide dichlorides (1) in excellent yields.Portionwise addition of 1 to a stirred two-phase mixture of an aqueous sodium dithionite solution and benzene gives α,α'-diketo
