The cationic uranium amide compound [U(Cp * )2(NMe2)(THF)][BPh4] 1 (Cp * = η-C5Me5, THF = tetrahydrofuran) was transformed into the heterocyclic metallacycle [(Cp*)2U(O(CH2)4NMe2(CH2)4O)][BPh4] ·0.5THF 2 in the presence of a catalytic amount of the free amine NR2H (R = Me, Et). Treatment of 1 with tBuNC afforded the isocyanide adduct [U(Cp * )2(NMe2)(CNtBu)2][BPh4] 4 whereas reactions with MeCN, CO2 and CO gave the insertion compounds [U(Cp * )2(NC{Me}{NMe2})(THF)][BPh4] 5, [U(Cp * )2(O2CNMe2)(THF)][BPh4] 6 and [U(Cp * )2(η2-CONMe2)(THF)][BPh4] 7. The crystal structure of a THF solvate of 4 has been determined. 1997 Elsevier Science S.A.
