The hydroxo complex [{Pd(μ-OH)(tmeda)}2][BPh4]2 (tmeda=N,N,N′,N′-tetramethylethylenediamine) reacts with a wide variety of weak protic electrophiles H(LL) in a 1:2 molar ratio to give the mononuclear cationic palladium(II) derivatives with the general formula of [Pd(LL)(tmeda)][BPh4] (LL=acetylacetonate (acac) (1); salicylaldehydate (sal) (2); salicylaldiminate (o-RN=CHC6H4O: R=CH(CH3)2 (3), C6H5 (4), p-ClC6H4 (5), p-BrC6H4 (6), p-MeC6H4 (7)); 2-pyrrole-carbaldehydate (pcal) (8); 2-pyridine-methoxo(OCH2-py) (9); picolinate (pic) (10); 8-hydroxyquinolinate (oxin) (11) or the dinuclear complexes [{Pd(μ-pz)(tmeda)}2][BPh4]2 (12) and [{Pd (tmeda)}2(μ-OH)(μ-HNC6H4R-p)][BPh 4]2 (R=H (13), Cl (14) or Me (15)) when reacting with pyrazole or anilines in the same molar ratio. In a related reaction, deprotonation of secondary amines by the hydroxo complex in the presence of carbon disulfide leads to the corresponding dithiocarbamate complexes [Pd(S2CNR2)(tmeda)][BPh4] R=Me (16), Et (17) C5H10 (18). The new compounds have been characterized by partial elemental analyses, conductance measurements and spectroscopic (IR, 1H and 13C NMR) methods. The crystal structure of compound 14 has been determined by X-ray diffraction analysis.
