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

Abstract

Abstract 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.
