title: Synthesis of uranium-ligand multiple bonds by cleavage of a trityl protecting group.
abstract: Addition of KSCPh3 to [U(NR2)3] (R = SiMe3) in tetrahydrofuran, followed by addition of 18-crown-6, results in formation of the U(IV) sulfide, [K(18-crown-6)][U(S)(NR2)3] (1) and Gomberg's dimer. Similarly, addition of KOCPh3 to [U(NR2)3] in tetrahydrofuran, followed by addition of 18-crown-6, results in formation of the U(IV) oxide, [K(18-crown-6)][U(O)(NR2)3] (3). Also observed in this transformation are the triphenylmethyl anion, [K(18-crown-6)(THF)2][CPh3] (5), and the U(IV) alkoxide, [U(OCPh3)(NR2)3] (4).
