Silver perrhenate

As no simple copper-perrhenate salts previously existed to serve as a model for structural relationships to [Cu2(pzc)2(H20)2Re04], our attention turned to the syntheses of the isoelectronic silver-perrhenate systems. Shortly after an analysis of the structure above, a synthesis of the new pyrazine-pillared (=pyz) AgRe04(pyz) solid was found [30], and is shown in Fig. 17.3 alongside the re-... [Pg.255]

One and thirty-five hundredths grams of silver perrhenate is added, with stirring, to 10 ml. of dry hexamethyldisiloxane in a 100-ml. round-bottomed flask. One milliliter of tri-methylchlorosilane is added. The mixture is stirred for... [Pg.150]

The silver perrhenate, especially, forms reproducible, analytically pure, off-white MTO [8]. Selected catalytic applications of MTO are treated in Section 3.3.13.1. [Pg.1320]

The following reagents and respective amounts are needed 1.5 L of acetonitrile, 1400 g (39 mol) of silver perrhenate [AgRe04], 1080 mL (85 mol) of trimethylchlorosilane [ClSi(CH3)3], 600 mL (4.3 mol) of tetramethyltin.The quick formation of the reactive intermediate species is indicated by the spontaneous precipitation of silver chloride after the silver perrhenate and the trimethylchlorosilane are mixed together. Yield 780-880 g (80-90%). [Pg.1321]

From earlier results, we now report in detail on the large-scale synthesis of MTO starting from silver perrhenate. The reaction involves the activation of the perrhenate with 2 equiv of TMSCl followed by alkylation with tetramethyltin ... [Pg.110]

Silver perrhenate, chlorotrimethylsilane, hexamethyldisiloxane, nitrogen cylinder. [Pg.22]

Silver perrhenate (dry commercial product, 2.35 g, 2.1 mmol) is placed in the reaction flask and suspended in hexamethyldisiloxane (dry commercial product, 25 niL). The two connected flasks... [Pg.22]

Trimethylsilyl perrhenate is also formed in the reaction of dichlorodimethylsilane with silver perrhenate in hexamethyldisi-loxane through a transesterification (yield 70%). The reaction and work-up follow the same procedures as described for Route 1 above ... [Pg.24]
