General Description
4-Iodotoluene undergoes Suzuki-Miyaura coupling reaction with phenylboronic acid catalyzed by (Ni,Mg)3Si2O5(OH)4 solid-solution nanotubes loaded with palladium. Cobalt-catalyzed coupling of 4-iodotoluene with thiophenols and alkanethiols has been investigated. Palladium/copper-catalyzed Sonogashira cross-coupling reaction of 4-iodotoluene with phenylacetylene has been studied.
Purification Methods
Crystallise 4-iodotoluene from EtOH and.or distil it. [Beilstein 5 IV 840.]
