Cupric fluoride

Copper(II) forms several stable fluorides, eg, cupric fluoride [7789-19-7J, Cup2, copper(II) fluoride dihydrate [13454-88-1],] Cup2 and copper... [Pg.180]

Although both cuprous and cupric fluorides have been studied in the past, an active fluorine donor can be formed from cupric oxide and hydrogen fluonde. This donor, in combination with 2,2 -bipyridine, effectively displaces the halogen of... [Pg.192]

Coppers second oxidation state (+2) forms cupric compounds, also referred to as copper(II), which are more stable than copper(l) compounds. For example, copper in both oxidation states can combine with fluorine for copper(I) or cuprous fluoride, Cu" " + F CuF and for copper(ll) or cupric fluoride, Cu " " + 2F —> CuF. ... [Pg.111]

The Jahn-Teller effect enhances the structural diversity of Cu(II) compounds [68], Most of the octahedral complexes of Cu2+, for example, show elongated tetragonally distorted geometry. Crystalline cupric fluoride and cupric chloride both have four shorter and two longer copper-halogen interatomic distances, 1.93 vs. 2.27 A and 2.30 vs. 2.95 A, respectively [69],... [Pg.300]

Cuprous fluoride, CuF.—The fluoride has been prepared by the interaction of hydrogen fluoride and cuprous chloride, and also by the dissociation of cupric fluoride, both processes taking place at a high temperature.9 The product of the action of hydrogen-fluoride solution bn cuprous oxide10 appears to be impure copper only.11 The fluoride is a ruby-red solid. [Pg.261]

In analogy to the Au(I) and Pd(II) systems of Hayashi and Shibasaki, respectively, this process is proposed to proceed through a metalloenolate intermediate. The catalytically active metalloenolate species is generated upon desilylative metallation of the enol silane by the cupric fluoride complex. In support of the hypothesis that a soft-metal enolate is an intermediate in the reaction, the investigators have observed that the reaction can be successfully executed under conditions that directly promote transmetallation of the enol silane in the absence of fluoride (Scheme 22). When a solution of enol silane is successively treated with 10 mol % of either MeLi or (Bu4N)Ph3Sip2 at 0 °C, followed by 5 mol % of (S)-BINAP Cu(OTf)2 at -78 C and benzaldehyde, the aldol adduct was isolated... [Pg.998]

A film that is 3 mil thick can be completely fluorinated on a 100-mesh phosphor bronze gauze, if the reaction is allowed to proceed for several days [135]. Fluorination can also be carried out with mercuric or cupric fluorides in hydrofluoric acid. The reaction must be carried out at 110°C for 50 h. As much as 20% of fluorine can be introduced [136]. [Pg.590]
