Ph2P(O)C(S)N(H)R (R Me, Ph) reacts with M(CO)3(η5-C5H5)Cl (M Mo, W) in the presence of Et3N to give M(CO)2(η5-C5H5)(Ph2P(O)C(S)NR). The deprotonated ligand coordinates in a bidentate manner through N and S to give a four-membered ring system. M(CO)3(PPh3)2Cl2 (M Mo, W) reacts with Ph2P(O)C(S)N(H)R (R Me, Ph) in the presence of Et3N to give complexes in which the central metal atoms are seven
pH值2 P(O)C(S)N(H)R(RMe中,PH)与M(CO)反应3(η 5 -C 5 H ^ 5)氯(M的Mo,W)中的存在等3 N到得到M(CO)2(η 5 -C 5 H ^ 5)(PH 2 P(O)C(S)NR)。去质子化的配体通过N和S以双齿方式配位,得到四元环系统。M(CO)3(PPh 3)2 Cl 2(MMo,W )在存在Et 3的情况下与Ph 2 P(O)C(S)N(H)R(RMe,Ph)反应N形成配合物,其中中心金属原子为7个配位体,通过O和S结合的两个配体形成五元环系统,一个PPh 3和两个CO基团。通过元素分析,IR,1 H NMR和31 P NMR光谱以及Mo(CO)2(PPh 3)(Ph 2 P(O)C(S)NPh)的X射线结构分析对复合物进行表征2 ·CH 2 Cl 2。
