A New and Effective Synthesis of Terminal Alkylselenylacetylenes
A New and Effective Synthesis of Terminal Alkylselenylacetylenes
摘要
The terminal alkylselenylacetylenes (RSe-C = C-H) 3a-h were prepared by the reaction of ethynylmagnesium bromide at -20 degrees C in THF with alkylselenyl bromides derived from dialkyl diselenides and bromide.
