Acetimine and 2-Methyl-2-amino-4-iminopentane Complexes of Palladium(II)
摘要:
By reaction between the labile complex cis-[Pd(C6F5)(2)(PhCN)(2)] and aqueous ammonia-acetone solutions the palladium complexes [Pd(C6F5)(2)L-2] [L = NH3 (1), NHCMe2 (2) and L-2 = NHC(Me)CH2C(Me-2)NH2 (3)] are obtained. The reaction product depends on the experimental conditions used. The cationic complexes [Pd(dmba)L-2]ClO4 [L = NH3 (5), NHCMe2 (6) and L-2 = NH C(Me)CH2C(Me-2)NH2 (7)] with the N,C-chelating 2-(dimethyl-aminomethyl)phenyl (dmba) ligand have been obtained by treating [(dmba)Pd(mu-Cl)(2)Pd-(dmba)] with AgClO4 in aqueous ammonia-acetone solution. The mono(acetimine) complex [Pd(dmba)(PPh3)(NHCMe2)]ClO4 (8) is obtained by a similar procedure starting from [Pd-(dmba)(PPh3)Cl]. The crystal structures of 1-3 and 6 and 7 have been determined; there is extensive hydrogen bonding (N-H...F-C or N-H...OClO3) in all the compounds.
