With Selenides

An alternative procedure to effect elimination resolves this problem. Opening the oxaspiropentane 26 with selenide anion in a non-protic solvent effects a direct elimination via a merged substitution — elimination mechanism to give the vinyl-... [Pg.32]

Polymer stabilization is another area in which the peroxide-decomposing and chain-breaking antioxidant properties of diorganotellurides has found utUity. Alone or in combination with phenol and phosphate antioxidants, electron-rich dialkylamino-substirnted diaryltellurides and alkylaryltellurides provided greatly enhanced polymer stability for a thermoplastic elastomer and for polypropylene. The effects were unique to the tellurides, with selenides not providing similar protective effects. ... [Pg.140]

In acid media the sensitivity for divalent metals is decreased because of formation of HjS consequently electrodes with selenides are preferable in acid media [155], In the absence of complexes the electrodes have a response for divalent ions with Nernstian slope in the concentration range 10 to 10" moldm- ... [Pg.147]

This magnesium-dependent enzyme [EC 2.7.9.3], also known as selenide,water dikinase and selenium donor protein, catalyzes the reaction of ATP with selenide and water to produce AMP, selenophosphate, and orthophosphate. [Pg.633]

With selenides of the alkali metals and of tin, complex seleno-stanno-platinates have been obtained. The general formula M.,Se. SnSe2.3PtSe or M2SnPtjjSe8 is given to them, analogous to that for the thio-stanno-platinates, MJ3nPt8S4. [Pg.308]

Lastly, recent evidence suggests that the dithiolene may particpate in the substrate reaction in special cases. The short Se—S contact in FDH (35) observed by XAS is interpreted as an interaction that possibly replaced Mo-based redox with selenide-sulfide redox. [Pg.527]

The lower curves show the mechanically polished electrodes with a damaged surface layer and the upper curves the same after etching. Fig. 106.

Finally, the metidlation is particuliriy difficult with selenides bearing a methoxymethyl substituent, and is only successful when a m-(t uoromethyl)phenyl moiety is attached to the selenium atom (Scheme 21, a). [Pg.640]

A modest number of reports detailing the synthesis of selenophene derivatives have appeared. Treatment of cinnamaldehyde (256) with selenide 257 gave dihydroselenophene 258 . A formal [3+2] cycloaddition of selenide 259 with DMAD gave dihydroselenophene 260 . Novel tetrathiafulvene-fused selenophenes and... [Pg.104]
