Chiral organometallic reagents. Part XXIV.1 Iodine ate-complexes as intermediates in the iodine–lithium exchange reaction on 1,1-diiodoalkanes
Abstract
The iodine–lithium exchange reaction on the 1,1-diiodoalkanes 17 at –110 °C is initiated by the irreversible formation of yellow iodine ate-complexes, which are slowly transformed into the α-iodoalkyllithium compounds 21.
