Application of indium ate complexes to synthetic chemistry. Selective conjugate addition to enones and coupling with allylic halides
Abstract
Tetraorganoindium ate complexes, prepared by the addition of organolithium reagents to trialkylindium, reacted with α,β-unsaturated ketones in a 1,4-addition fashion; allylic indates derived from allylic indium sesquihalides coupled with allylic halides regio- and stereo-specifically to give high yields of head-to-tail 1,5-dienes.
