Migration 1,2 d'un groupe trimethylsilyle au niveau d'un cation vinylique: synthese de dienes conjugues silyles a partir de bis(trimethylsilyl)-1,4 alcynes-2

Article abstract of DOI:10.1016/0022-328X(88)80021-4

Alkyl α-substituted 1,4-bis(trimethylsilyl)-2-alkynes react with electrophilic reagents to give silylated conjugated dienes, which result from a 1,2-shift of a trimethylsilyl group to a vinylic cationic center.
