Triamidoamine-uranium(IV)-stabilized terminal parent phosphide and phosphinidene complexesTools Gardner, Benedict M. and Balázs, Gábor and Scheer, Manfred and Tuna, Floriana and McInnes, Eric J.L. and McMaster, Jonathan and Lewis, William and Blake, Alexander J. and Liddle, Stephen T. (2014) Triamidoamine-uranium(IV)-stabilized terminal parent phosphide and phosphinidene complexes. Angewandte Chemie International Edition, 53 (17). pp. 4484-4488. ISSN 1521-3773 Full text not available from this repository.AbstractReaction of [U(TrenTIPS)(THF)][BPh4] (1; TrenTIPS=N{CH2CH2NSi(iPr)3}3) with NaPH2 afforded the novel f-block terminal parent phosphide complex [U(TrenTIPS)(PH2)] (2; U–P=2.883(2) Å). Treatment of 2 with one equivalent of KCH2C6H5 and two equivalents of benzo-15-crown-5 ether (B15C5) afforded the unprecedented metal-stabilized terminal parent phosphinidene complex [U(TrenTIPS)(PH)][K(B15C5)2] (4; U[DOUBLE BOND]P=2.613(2) Å). DFT calculations reveal a polarized-covalent U[DOUBLE BOND]P bond with a Mayer bond order of 1.92.
