A variety of aryl vinyl selenides are prepared by reaction of vinyl Grignard reagents with aryl selenenyl bromides or by reductive elimination of the adducts of [bis (arylseleno) methyl] lithiums with carbonyl compounds. Deprotonation of phenyl vinyl selenide is achieved with LDA at-78 OC in THF. Vinyl selenides with j3-alkyl groups require LiTMP and warmer temperatures (-50" C) for complete deprotonation. Allylic lithium reagents were obtained ...
