A New and Effective Synthesis of Terminal Alkylselenylacetylenes

Department of Chemistry Hangzhou University Hangzhou 310028

Received Date: 6 July 1996

The terminal alkylselenylacetylenes (RSe-C≡C-H) 3a-h were prepared by the reaction of ethynylmagnesium bromide at -20℃ in THF with alkylselenyl bromides derived from dialkyl diselenides and bromide.
