A series of MoHg and WHg bonded complexes [RHgM(CO)3Cp], (R = 2,4,6-C6H2Cl3,2,3,5,6-C6,HCl4 and C6Cl5) have been prepared from ClHgR and the salts Na[M(CO)3)Cp]. When R contains only one ortho chlorine atom (R = 2,5-C6H3Cl2, 2,3,4-C6H2Cl3 and 2,3,4,5-C6HCl4) a symmetrisation process occurs to give the corresponding HgR2 and Hg[M(CO)3Cp)22. These results indicate that steric effects are very important
一系列MoHg和WHg结合复合物的[RHgM(CO)3的Cp](R = 2,4,6-C 6 H ^ 2氯3,2,3,5,6--C 6,由ClHgR和盐Na [M(CO)3)Cp]制备了HCl 4和C 6 Cl 5)。当R仅含有一个邻位的氯原子(R = 2,5--C 6 H ^ 3氯2,2,3,4-C 6 H ^ 2氯3和2,3,4,5--C 6盐酸4)一个symmetrisation产生相应的HgR 2和Hg [M(CO)3Cp)2 2.这些结果表明,空间效应对于形成包含钼或钨-汞键的化合物非常重要。从[(C 6 Cl 5)HgM(CO)3 Cp]获得[ [C 6 Cl 5)HgM(CO)2(PPh 3)Cp]型的配合物(M = Mo和W)。和PPh 3在沸腾的乙醇中。
