Halides reductions

Hydrogen reduction has a major advantage in that the reaction generally takes place at lower temperature than the equivalent decomposition reaction. It is used extensively in the deposition of transition metals from their halides, particularly the metals of Groups Va, (vanadium, niobium, and tantalum) and Via (chromium, molybdenum, and tungsten). The halide reduction of Group IVa metals (titanium, zirconium, and hafnium) is more difficult because their halides are more stable. [Pg.70]

Various options for the production of tantalum from pure tantalum compounds are summarized in Figure 4.26. The oxide and halide reduction reactions described above have been carried out in basically different types of reactors, using processes that are characteristically different because the forms and the physico-chemical nature of the feed materials are different. A relatively recent development with regard to process metallurgical equip-... [Pg.425]

Abstraction of one of the metal-bound hydrides from complex 5a provides the cationic iridium(lll) complex 28, which is an efficient precatalyst for alkyl halide reduction in the presence of EtsSiH (Equation 12.11) [31]. [Pg.317]

Excellent quality metal, comparable to that from the halide reduction, can be prepared by this technique. A big advantage is that no neutrons are present from (a,ra) reactions on fluorine nuclei, in marked contrast to the case with actinide fluorides. [Pg.7]

Acyl-sn-glycero-3-phosphoethanolamine, LYSOPHOSPHOLIPASE D Acyl halide reduction to alcohols (or aldehydes),... [Pg.719]

Radical chain processes break down whenever the velocity of a termination reaction is comparable to the velocity of the rate-controlling step in a chain reaction. This situation would occur, for example, if one attempted to use EtsSiH as the hydrogen atom donor in the alkyl halide reduction sequence in Figure 4.6 and employed typical tin-hydride reaction conditions because the rate constant for reaction of the silane with an alkyl radical is 4 orders of magnitude smaller than that for reaction of Bu3SnH. Such a slow reaction would not lead to a synthetically useful nonchain sequence, however, because no radical is persistent in this case. In fact, a silane-based radical chain reduction of an alkyl halide could be accomplished successfully if the velocity of the initiation reaction was reduced enough such that it (and, hence, also the velocity of alkyl radical termination... [Pg.138]

The generation of silyl radicals, species which have proven to be of great value in both mechanistic and synthetic studies, was reported independently in 1947 by Sommer and Whitmore (equation 63), " and by Barry et al. at Dovvf Chemical. " These are useful for many purposes, including halide reductions. " ... [Pg.27]
