Reaction chemistry of [Pd-2(mu-OH)(2)L-4](2+) with aryl amines. Structures of [Pd-2(mu-OH){mu-NH(p-tol)}(PPh3)(4)](BF4)(2), [Pd(eta(3)-CH2C(NH(p-tol)CH2)(PPh3)(2)](BF4), and [Pd(PMe2Ph)(2)(mu-PF2O2)](2)(PF6)(2)

摘要

The reaction of [Pd-2(mu-OH)(2)(PPh3)(4)](BF4)(2) (1) with aromatic amines (aniline and p-toluidine) in dichloromethane yields the dinuclear complexes [Pd-2(mu-OH)(mu-NHAr)(PPh3)(4)](BF4)(2) (2) (Ar =Ph, p -tol). The same reaction in acetone gives the palladium(II) allyl complex, [Pd(eta(3)-CH2C(NHp-tol)CH2)(PPh3)(2)](BF4) (3). An attempt to prepare the PMe2Ph analog of I as the PF6- salt yielded instead [Pd(PMe2Ph)(2)(mu-PF2O2)](2)(PF6)(2) (7). The structures of 2 (Ar = p-tol), 3, and 7 have been determined by X-ray diffraction methods. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 44]
