The treatment of 1 with Hdppa {Hdppa = N,N-bisdiphenyl phosphinoamine} in refluxing dichloromethane yielded the doubly bridged Hdppa dipalladium complex [Pd(Br)]2(\u03bc,\u03b72-Hdppa)2, 4. Complex 1 reacted with the bidentate ligand, NH4S2CNC4H8 and, NaS2COEt, and the tridentate ligand, KTp {Tp = tris(pyrazoyl-1-yl)borate}, to form the \u03b72-dithio \u03b71-pyrimidinyl complex [Pd(PPh3)(\u03b71-C4H3N2)(\u03b72-SS)], (5: SS = S2CNC4H8; 6: SS = S2COEt) and \u03b72-Tp \u03b71-pyrimidinyl complex [Pd(PPh3)(\u03b71-C4H3N2)(\u03b72-Tp)], 7, respectively. Treatment of 1 with AgBF4 in acetonitrile at room temperature resulted in the formation of the doubly bridged \u03b72-pyrimidinyl dipalladium complex [{Pd(PPh3)(CH3CN)}2(\u03bc,\u03b72-C4H3N2)2][BF4]2, 8.
