the tetranuclear compound [Pd4-MeOC6H3C(Me)═NN═C(S)NHMe}]4 (2), with the ligand as terdendate [C,N,S]. Reaction of 2 with the diphosphines Ph2PCH2PPh2 (dppm), Ph2PC(═CH2)PPh2 (vdpp), and Ph2PC(CH2)2PPh2 (dpcp) gave the mononuclear complexes [Pd4-MeOC6H3C(Me)═NN═C(S)NHMe}(L)] (L = dppm-P, 3; dpcp-P, 4; vdpp-P, 5) with the diphosphine ligand binding in a monodentate fashion. Compounds 3−5 may bond systematically
用四氯钯酸钾处理4-MeOC 6 H 4 C(Me)═NN(H)C(═S)NHMe(1),得到四核化合物[Pd 4-MeOC 6 H 3 C(Me)═NN═ C(S)NHMe}] 4(2),其配体为叔丁酸酯[ C,N,S ]。的反应2与二膦博士2 PCH 2 PPH 2(DPPM)中,Ph 2 PC(= CH 2)PPH 2(vdpp),且Ph 2 PC(CH 2)2 PPH 2(dpcp)得到单核络合物[Pd 4-MeOC 6 H 3 C(Me)═NN═C(S)NHMe}(L)](L = dppm-P,3 ; dpcp-P,4 ; vdpp- P,5)与二膦配体以单齿方式结合。化合物3 - 5可以系统地粘结到第二金属原子,钯或铂,通过noncoordinated磷原子和缩氨基硫脲基团的硫原子,得到双核化合物6 - 10,从而表现为二齿P,小号-palladacycle metalol
