Copper(I) Iodide-Promoted Allylation of Allyl-and Vinyl-silanes Assisted by Intramolecular-Coordination
The allylation products, 1-(2-pyridylthio)alk-1,5-dienes, were produced regioselectively when 1-(2-pyridylthio)-1-(trimethylsilyl)alk-2-enes were treated with allylic chlorides in the presence of CuI and KF. The similar reaction of 1-(2-pyridylthio)-1-(trimethylsilyl)alk-1-enes with allylic chlorides produced the 1,4-dienes with complete retention of configuration.
