The short-bite ligands CH2(PR
2)2 or CH(PR
2)3 (R = Me, Ph),RN(PX
2)2 (R=H, Me, Et;X = F, OR (R= Me, Et, i-Pr, Ph), Ph),RE(CH2
ER2)2 (E = P, As;R = Me, Ph ), Ph2 P(2-C5H4N) and related species are particularly versatile for the synthesis of di- and polynuclear complexes which frequently possess metal-metal bonds. In addition to homometallic products, these ligands often permit the directed synthesis of heterometallic complexes. Selected aspects of the chemistry of these complexes are also reviewed. 相似文献

The four-coordinate tin(II) complex [η4-Me8taa]Sn undergoes oxidative addition of I2 to give six-coordinate [η4-Me8taa]SnI2, in which the iodide ligands exhibit a trans arrangment. Abstraction of I− from [η4-Me8taa]SnI2 is facile, as indicated by the rapid formation of the triiodide derivative *[η4-Me8taa]SnI(THF)**I3* upon treatment with I2 in the presence of THF. The molecular structures of [η4-Me8taa]SnI2 and *[η4-Me8taa]SnI(THF)**I3* have been determined by X-ray diffraction. 相似文献

Quadruply bonded metal-metal (M4-M)comptexes in electronic excited stares exhibit a rich oxidation-reduction chemistry. The structural, electronic, and oxidation-reduction properties of M4-M complexes may be exploited to rationally design their excited state chemistry from conventional one-electron pathways to the first Iogical development of discrete multielectron pathways. As we commemorate the 30-year anniversary of the discovery of M4-M complexes by F. A. Cotton, this review shows that they currently provide chemistry with some of the most diverse and novel reactivity for transition metal complexes in the excited state. 相似文献
