Abstract
When 1,4-diiodo-1,3-alkadienes were treated with i-PrBu2MgLi, highly site-selective iodine−magnesium exchange reaction took place to afford, after the reaction with electrophiles, a variety of 1-iodo-1,3-alkadiene derivatives. Synthetic utility of the reaction was demonstrated by an efficient preparation of polysubstituted styrenes and phenols.
