Abstract: The synthesis of unsymmetrical pincer ligands by reactions of diphenyl disulfide and diphenyl diselenide with bis(2-chloroethyl) ether in the system hydrazine hydrate–KOH was accompanied by the formation of 1,2-bis(phenylsulfanyl)ethane, 1,2-bis(phenylselanyl)ethane, and 1-(phenylselanyl)-2-(phenylsulfanyl)ethane as by-products with an overall yield of 23% as a result of nucleophilic cleavage of the C–O–C bond in the initial ether.

The air- and moisture-insensitive half-sandwich complexes [(η5-Cp)Rh(L)Cl][PF6] (1-3) and [(η5- Cp)Ir(L)Cl][PF6] (4-6) have been prepared by reacting L = L1-L3 (1,2-bis(phenylthio)ethane (L1), 1-(phenylseleno)-2-(phenylthio)ethane (L2) and 1,2-bis(phenylseleno)ethane (L3)) with [(η5-Cp)RhCl(μ-Cl)] 2 and [(η5-Cp)IrCl(μ-Cl)]2, respectively, at room temperature followed by treatment with NH 4PF6. Their HR-MS and 1H, 13C{ 1H}, and 77Se{1H} NMR spectra have authenticated them. The single-crystal structures of 1-6 have been established by X-ray crystallography. Complexes 1-6 have been explored for catalytic Oppenauer-type oxidation of alcohols and transfer hydrogenation of ketones with 2-propanol. 3 and 6 were the most efficient in the two catalytic reactions (TON values up to 9.9 × 102 and 9.8 × 103, respectively) and were therefore investigated in detail. 3 is the first example of a Rh(III) species explored for Oppenauer-type oxidation. The catalysis appears to be homogeneous. In transfer hydrogenation it appears that one of the catalytic species is without a Cp* ring. DFT calculations indicate higher reactivity for Rh complexes in comparison to Ir complexes. This order has also been found for the two catalytic reactions experimentally. The calculated bond lengths/angles by DFT are generally consistent with the experimental values.

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 chalc

While the tin tetrachloride mediated addition of dimethyldiselenide to mono- and disubstituted olefins proceeds rapidly and with good yields in most of the cases, diphenyldiselenide appears to react less efficiently.

A convenient synthesis of MeSeLi from MeLi and Se8 in tetrahydrofuran (THF) has been used to prepare the bis-selenoethers MeSenSeMe (n = 1,2,3,6, or 12) and cis-MeSeCH=CHSeMe.PhSenSePh (n = 1-3) and cis-PhSeCH=CHSePh have been prepared from PhSe-, itself produced from Ph2Se2 and LiALH4-THF or sodium hydroxymethanesulphinate.The bis-selenoethers o-C6H4(SeR)2 (R = Me or Ph) were obtained from R2Se2 and benzyne.The syntheses of (RSeCH2)3CMe (R = Me or Ph), (MeSeCH2)4C, and (MeSeCH2CH2CH2)2Se are also described.The 1H, 13C, and 77Se n.m.r. spectra of these selenoethers have been recorded, and the chemical shifts and coupling constants (nJSe-H, nJSe-C) are discussed in terms of structures.Mass spectra of the selenoethers have been recorded and the principle fragmentation modes identified.
