Cerium tetrakis(diisopropylamide) - a useful precursor for cerium(IV) chemistry

Homoleptic cerium(IV) diisopropylamide was synthesized via oxidation of ate complex Ce(NiPr2)(4)Li(thf) with trityl chloride or hexachloroethane. Due to its ready accessibility, and high pK(a) value of the proligand HNiPr2, Ce(NiPr2)(4) features a promising candidate for protonolysis reactions, as shown for the synthesis of dimeric cerium(IV) tetrakis(1,1,3,3-N,N,N',N'-tetramethylguanidinate).
