Convenient Syntheses of N,N-Dialkylselenoamides and N,N,N',N'-Tetraalkylselenoureas by Treating Terminal gem-Dihaloalkanes, Chloroform , or Sodium Trichloroacetate with a Base, Elemental Selenium, and Amines

Article abstract of DOI:10.1246/cl.1994.2105

Treatment of terminal gem-dihaloalkanes, chloroform or sodium trichloroacetate with elemental selenium in the presence of NaH and an excess amount of primary or secondary amines gave selenoamides and selenoureas in modest yields.
