“…If the addition is carried out rapidly, formation of a black precipitate occurs, as previously reported [2]. When nitrogen is bubbled into the reaction mixture during the addition of NaBH 4 All the compounds containing SbPh 3 described in this paper are insoluble in the usual solvents and they could not be recrystallized.…”

“…When [PtCl 2 (PPh 3 ) 2 ] is treated with N 2 H 4 in the presence of PPh 3 and an acetylenic compound (ac), complexes of the type [Pt(ac)(PPh 3 ) 2 ] are formed, in which the acetylene ligand is labile [24][25][26] 4 ]. It may be that steric hindrance in the case of SbPh 3 is larger than for PPh 3 and AsPh 3 and this can be a limiting factor for the existence of the complex [Pt(SbPh 3 ) 4 ].…”

The reactivity of [Pt(SbPh 3 ) 3 ], a compound of zerovalent platinum, exceptionally stable in air, is described. The compounds [{Pt(SbPh 3 ) 3 } 2 N 2 ], containing bridging dinitrogen, [{Pt(SbPh 3 ) 3 } 2 C 2 ], with an ethynediyl group also bridging, and [Pt(CO) 2 (SbPh 3 ) 2 ], were all obtained under ordinary pressure of nitrogen, acetylene or carbon monoxide, respectively, and are also described. Among the products of the reactions, the dimer [PtBr 3 (SbPh 3 ) 2 ] 2 and the mixed complexes [PtL 2 (SbPh 3 ) 2 ] (L = PPh 3 , AsPh 3 ) were also obtained. Some of these complexes are luminescent when excited by u.v. radiation.

Hydrogen Peroxide Synthesis: An Outlook beyond the Anthraquinone Process

2006

Hydrogen peroxide (H2O2) is widely used in almost all industrial areas, particularly in the chemical industry and environmental protection. The only degradation product of its use is water, and thus it has played a large role in environmentally friendly methods in the chemical industry. Hydrogen peroxide is produced on an industrial scale by the anthraquinone oxidation (AO) process. However, this process can hardly be considered a green method. It involves the sequential hydrogenation and oxidation of an alkylanthraquinone precursor dissolved in a mixture of organic solvents followed by liquid-liquid extraction to recover H2O2. The AO process is a multistep method that requires significant energy input and generates waste, which has a negative effect on its sustainability and production costs. The transport, storage, and handling of bulk H2O2 involve hazards and escalating expenses. Thus, novel, cleaner methods for the production of H2O2 are being explored. The direct synthesis of H2O2 from O2 and H2 using a variety of catalysts, and the factors influencing the formation and decomposition of H2O2 are examined in detail in this Review.

“…When the metal hydride formed is unstable (as in the case of Pd), the reaction can be used as the basis for a catalytic conversion of alcohols (9, 10) (Reaction 5 and of isocyanides to isocyanates (28-30) as well as oxidations of S02 (31), CO (32), NO, and N02 (33) should be mentioned.…”

Research in catalysis by coordination complexes has resulted in the discovery of many new reactions and the development of several important industrial processes. Close parallels to heterogeneous and biocatalysis are indicated. Progress in reaching a detailed understanding of homogeneous catalytic reactions has been slower. Problems encountered are that nonisolable catalytic species may form in situ, kinetic studies often provide only limited mechanistic information, observed rates and products are affected strongly by media and catalyst compositions, and analogies between apparently closely related systems are frequently invalid. Difficulties in commercialization include containment of corrosive systems and product isolation from liquid media. These problems appear resolvable by currently available means. It is expected that continued research will lead to new applications and will contribute substantially to improved understanding of catalytic phenomena in general."p\uring the past decade homogeneous catalysis has progressed from an interesting novelty to its present status as a recognized field. In the interval a great deal has been said and written concerning the subject, much of it well beyond the scope of this discussion which is limited to an indication of what has been accomplished, an outline of the problems which have been encountered, and a forecast of future prospects.In the strictest sense, homogeneous catalysis involves catalytic reactions occurring in a single phase. However, as currently used, the term implies only that at least a portion of a particular reaction is known or suspected strongly to occur in the coordination sphere of a metal (most frequently a transition metal). Activation of substrates and likely the steric course of the reaction are then consequences of bonding in an in- 197Downloaded by UNIV OF CALIFORNIA SAN DIEGO on June 4, 2015 |
