Zirconium copper

Organometallic compounds, such as organomercury, boron, aluminum, zirconium, copper, silane, lead, and bismuth, can also be utilized for the coupling reactions, although these methods have not been studied extensively.

The present fuel is made of stainless steel clad uranium oxide, but low absorbing can materials have been developed. Six channels of the reactor are loaded with zirconium-copper clad bundles, and their number will be progressively increased during the next two years, since Irradia-... 

The further development of this reactor line is closely linked to the applicability of natural uranium. When the last hopes regarding the suitability of beryllium as cladding material vanished about two years ago, attention was focussed upon the development of suitable zirconium alloys. Hitherto, the evaluation of irradiated test fuel elements with zirconium-copper canning has been rather encouraging, but the experience gained so far is yet too small to form the basis of... 

There Is also a certain connection between the efforts to bring down the Investment costs and the considerations and exertions for the development of C02 gas turbines aimed at the realization of a direct circuit, which could obviously be utilized as well for a COg cooled heavy water reactor. Hot gas temperatures in the range of 500°C which. In connection with zirconium-copper as cladding may be regarded today as quite realistic, would result In a rather Interesting overall efficiency of a plant. The most attractive point, however, in connection with a process based on an expansion to not less than about 80 kg/cm -the kind of process we would prefer - Is given by the remarkably small dimensions of the CO2 turbines of such a plant.

Aniline has been intercalated into the acidic host matrices of HFe(S04)2.4H20,andof a-Zr(HPOP2.H20 and y-ZrOIPOPj H O, and their partially copper exchanged phases. The nature of the guest species neutral, protonated or polymerised, depends on the inorganic template. Polymerised aniline has been identified in both a and y modifications of zirconium copper hydrogen phosphates.

While many other metals can be used for transmetalation from alkyl- and alkenylzirconocenes [4], the synthetically most important protocols include cross-couplings after zirconium palladium and zirconium- nickel trans-metalations, and carbon-carbon bond formation after zirconium zinc and zirconium copper transmetalations. Recent advances in these transformations and their synthetic scope are discussed in more detail below.
