Abstract In this article we present the results of a study on the synthesis of In–E–MI ternary clusters (E = S, Se; MI = Cu, Ag) and an evaluation of the optical band gap energy. Characterization of three new compounds is reported: [Cu2In(PPh3)2SPh(μ-SPh)4] (1), [Cu2In(PPh3)2SePh(μ-SePh)4] (2) and [Ag2In(PPh3)2SPh(μ-SPh)4] (3). We discuss the hard-soft migratory tendency of the chalcogenolate ligands
摘要在本文中,我们介绍了In-E-MI三元团簇(E = S,Se; MI = Cu,Ag)的合成研究以及对光带隙能量的评估的结果。报告了三种新化合物的表征:[Cu2In(PPh3)2SPh(μ-SPh)4](1),[Cu2In(PPh3)2SePh(μ-SePh)4](2)和[Ag2In(PPh3)2SPh(μ -SPh)4](3)。我们讨论了硫属元素配体在所涉及的金属中心之间的软硬迁移趋势。另外,描述了用于获得纯结晶形式的所需产物的实验条件。这些方法可在短时间内提供良好的产量,并且可以获得用于有趣材料的单一来源的前体。

An organoindium compound with an In-Se bond, [(Me3CCH2)2InSePh]2, has been synthesized and characterized by elemental analyses, IR, H-1 NMR, and C-13 NMR spectroscopy, cryoscopic molecular weight studies, and an X-ray structural study. The dimeric molecule crystallizes in the centrosymmetric monoclinic spacegroup P2(1)/c (No. 14) with a = 18.973 (4) angstrom, b = 10.105 (1) angstrom, c = 19.998 (6) angstrom, beta = 103.66 (2)-degrees, V = 3725.4 (14) angstrom3, and Z = 4. Diffraction data (Mo K-alpha, 2-theta = 5-45-degrees) were collected on a Siemens R3m/V automated four-circle diffractometer, and the structure was solved and refined to R = 3.44% and R(w) = 3.73% for those 2557 unique data with \F(o)\ > 6-sigma(\F(o)\) (R = 8.35% for al 4891 data). The four-membered ln2Se2 ring has a butterfly arrangement with the phenyl groups in the anti position relative to the ring. The In-C(neopentyl) distances range from 2.135 (11) to 2.168 (10) angstrom, while In-Se bond distances range from 2.748 (1) to 2.756 (1) angstrom. There is some rotational disorder of the methyl groups within (at least) one of the methyl (-CH2CMe3) groups.

A fast and efficient phenylselenylation of allyl acetates by diphenyl diselenide and indium(I) bromide has been achieved in neat under the catalysis of Ru(acac)3. The intermediate complex of diphenyl diselenide and indium has been isolated and identified as a polymeric pentacoordinated In(III) selenolate complex, [In(SePh)3]n.

Indium(III) benzenechalcogenolates (chalcogen = sulfur and selenium) promote the rigorous Markovnikov hydrochalcogenation of terminal alkynes. The generality and limitations of the reaction with aminoalkynes leading to allylic amines bearing vinylic chalcogenide substituents are discussed.
