Reaction chemistry of [Pd2(μ-OH)2L4]2+ with aryl amines.
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.
