Synthesis of cationic uranium compounds by protonolysis of amide precursors: cyclopentadienyl and cyclooctatetraene complexes

Abstract
The cationic organouranium(IV) compounds [U(η-C5H5)3(thf)]BPh4(thf = tetrahydrofuran)1, [U(η-C5Me5)(NEt2)2(thf)2]BPh42, [U(η-C5R5)2(NEt2)(thf)]BPh4(R = H 3 or Me 4), [U(η-C5Me5)2(NMe2)(thf)]BPh45, [U(η-C8H8)(NEt2)(thf)2]BPh46, [U(η-C5R5)(η-C8H8)(thf)2]BPh4(R = H 7 or Me 8) have been synthesized from the neutral amide precursors by protonolysis of the U-NR2(R = Et or Me) bond with NHEt3BPh4; the crystal structures of 2 and 8 have been determined.
