講演概要
We have progressed metal based syntheses using rare earth metals considerably over the past several years. Organo-mercury and -thallium reagents have been extremely versatile reagents in redox transmetallation while the mercury reagents have also found great utility in the more convenient redox transmetallation/protolysis reactions. We have now extended this rare earth chemistry to the use of less toxic reagents such as RSnMe_3 , BiPh_3 , and most recently using pseudo-Grignard type chemistry and use of I_2 to activate the metal. This presentation will involve a discussion of the latter two methods.
In lanthanoid pseudo-Grignard chemistry, we have been able to use these reagents in protolysis reactions to deliver heteroleptic iodo(metal organic)lanthanoid species in good yield, despite previous reports of the mixed oxidation state for PhLnI (Ln = Eu, Yb). The species obtained our attempts to crystallise “PhYbI(thf)_n ” complexes will be presented.
We have recently shown that bulk lanthanoid metal can be activated by a few % of iodine crystals in the presence of a protic ligand to produce metal-organic compounds. In this presentation, the new directions of the project will be discussed along with the most recent exciting results.
