The first chiral diselenide 9 having an ortho-azomethine functional group has been synthesized by the reaction of bis(o-formylphenyl) diselenide with the chiral amine R(+)-(1-phenylethylamine). The chiral diselenide 9 was further characterized by derivati

Iodine oxidation of bis[2-(hydroxyiminomethyl)phenyl] dichalcogenides yields benzo-1,2-chalcogenazole 2-oxides. Annulated derivatives of iso-tellurazole N-oxides spontaneously aggregate into cyclic tetra- and hexamers through Te?O chalcogen bonding; the s

A series of N2Se2 and N2Se2O2 acyclic Schiff base diselenides (3-9) have been synthesized by condensation of bis(o-formylphenyl) diselenide and amines (aniline, p-bromoaniline, benzylamine, ethanolamine, 1-aminopropanol, 2-aminophenol). The Schiff base diselenides were characterized by elemental analysis, ESI-MS, NMR (1H, 13C, 77Se) spectroscopy and X-ray crystallography. During crystallization compound 6 afforded bis(phenyloxazoline) diselenide 9 via cyclization of Schiff base of ethanolamine. The supramolecular nature of these diselenides is studied by X-ray crystallographic structure analysis.

Several new diorganodiselenides containing (imino)aryl groups, [2-(RNCH)C6H4]2Se2 [R = Me 2NCH2CH2 (4), O(CH2CH 2)2NCH2CH2 (5), PhCH2 (6), 2′,6′-iPr2C6H3 (7)] were obtained by reacting [2-{(O)CH}C6H4] 2Se2 (3) with RNH2. Treatment of the diselenides 6 and 7 with stoichiometric amounts of K-selectride or Na resulted in isolation of the selenolates K[SeC6H4(CHNCH 2Ph)-2] (9) and Na[SeC6H4(CHNC 6H3iPr2-2′,6′)-2] (10), respectively. The reaction of potassium selenolates with anhydrous ZnCl 2 (2:1 molar ratio) gave Zn[SeC6H4(CHNCH 2Ph)-2]2 (11) and Zn[SeC6H 4(CHNC6H3iPr2-2′, 6′)-2]2 (12). When the dark green solution obtained from diselenide 7 and an excess of Na (after removal of the unreacted metal) was reacted with anhydrous ZnCl2 a carbon-carbon coupling reaction occurred and the 9,10-(2′,6′-iPr2C 6H3NH)2C14H10 (8) species was obtained. The compounds were investigated in solution by multinuclear NMR (1H, 13C, 77Se, including 2D and variable temperature experiments) and by mass spectrometry. The molecular structures of 6, 8, 11 and 12 were established by single-crystal X-ray diffraction. All compounds are monomeric in the solid state. In the diselenide 6 the (imino)aryl group acts as a (C,N)-ligand resulting in a distorted T-shaped coordination geometry of type (C,N)SeX (X = Se). For the zinc complexes 11 and 12 the (Se,N) chelate pattern of the selenolato ligands results in tetrahedral Zn(Se,N) 2 cores. The Royal Society of Chemistry 2012.

To investigate the nature of nonbonded Se...O interactions, three series of 2-substituted benzeneselenenyl derivatives [2-(CHO)C6H 4SeX (1), 2-(CH2OH)C6H4SeX, (2), 2-(CH2OPr)C6H
LITHIUM DISELENIDE IN APROTIC MEDIUM - A CONVENIENT REAGENT FOR SYNTHESIS OF ORGANIC DISELENIDES
Syper, Ludwik,Mlochowski, Jacek
, p. 6119 - 6130 (2007/10/02)
The reduction of selenium with lithium in THF in the presence of diphenylacetylene as a catalyst afforded lithium diselenide, which reacted with electrophiles giving alkyl or aryl diselenides 1 - 3 and selenides 4, as by-products.The useful method for preparation of diselenides based on this reaction was elaborated.
