Abstract

The Se—C_sp bond of selenium alkynides was cleavaged by Cp₂TiCl₂/i-BuMgBr in THF at room temperature to produce quantita-tively the selenium-free alkynes and deep blue titanocenium selenides Cp₂TiSeAr. The latter was converted into diaryldiselenides in air and reacted with acyl chloride in THF-HMPA to afford the cor-responding selenoesters in high yieds.

Key words: titanocene dichloride, selenium alkynide, acyl chloride, selenoester, isobutylmagnesium bromide
