  • Bestimmung der ionenpaar-basizitǎt von lithium- und kaliumamiden

    Ion pair basicities of lithio and potassio salts of some secondary amines were determined by equilibration with benzyl compounds. With these bases it is possible to span a range of about 19 pK-units from pK = 27 up to 46. The structural dependence of thermodynamic as well as kinetic basicity is discussed. Some new effective amide bases for preparative purposes are recommended. For the first time the

    The reaction between various bis(dialkylamino)chlorophosphines and N-isopropyl-substituted lithium amides afforded bis(α,α′-phosphino)imines in a ‘one-pot’ procedure. These compounds react with sulfur to generate intramolecularly hydrogen-bonded ylide derivatives. The molecular structure of (Pr2iN)2PCH2C(NBut)CH2P(NPri)2 has been determined by X-ray crystallography.

  • Experimental and DFT Computational Study of β-Me and β-H Elimination Coupled with Proton Transfer: From Amides to Enamides in Cp*<sub>2</sub>MX (M = La, Ce)
    作者:Sergio S. Rozenel、Lionel Perrin、Odile Eisenstein、Richard A. Andersen

    The thermal rearrangement of the f-block metallocene amides Cp-2*MNR1R2, where R-1 is CHMe2, R-2 is either CHMe2 or CMe3, and M is either La or Ce, to the corresponding enamides Cp-2*MNR1[C(Me)=CH2] and H-2 or CH4, respectively, occurs when the solid amides are heated in sealed evacuated ampules at 160-180 degrees C for 1-2 weeks. The net reaction is a beta-H or beta-Me elimination followed by a gamma-abstraction of a proton at the group from which the beta-elimination occurs. When R-1 is either SiMe3 or SiMe2CMe3 and R-2 is CMe3, the enamide Cp-2*MNR1[C(Me)=CH2] is isolated, the result of beta-Me elimination, but when R-2 is CHMe2, the enamides Cp-2*MNTR1[C(Me)=CH2] and Cp-2*NR1[C(H)=CH2] are isolated, the result of beta-H and beta-Me elimination. In the latter cases, both enamides are formed in similar amounts and the rates of the beta-H and beta-Me elimination steps must be similar. A two-step mechanism is developed from DFT calculations. The first step is migration of a hydride or a methyl anion to the Cp-2*M fragment, forming M-H or M-Me bonds as the N=C bond in the intermediate imine forms. The enamide evolves from the metal-coordinated imine by abstraction of a proton from the gamma-carbon of the intermediate imine. The two elementary steps involve significant geometrical changes within the N alpha C beta C gamma set of atoms during the two-step elimination process that are in large part responsible for the relatively high activation barriers for the net reaction, which may be classified as a proton-coupled hydride or methyl anion transfer reaction.
