The ITIES with an adsorbed monolayer of surfactant has been studied as a model system of the interface between microphases in a bicontinuous microemulsion [39]. This latter system has important applications in electrochemical synthesis and catalysis [88-92]. Quantitative measurements of the kinetics of electrochemical processes in microemulsions are difficult to perform directly, due to uncertainties in the area over which the organic and aqueous reactants contact. The SECM feedback mode allowed the rate of catalytic reduction of tra 5-l,2-dibromocyclohexane in benzonitrile by the Co(I) form of vitamin B12, generated electrochemically in an aqueous phase to be measured as a function of interfacial potential drop and adsorbed surfactants [39]. It was found that the reaction at the ITIES could not be interpreted as a simple second-order process. In the absence of surfactant at the ITIES the overall rate of the interfacial reaction was virtually independent of the potential drop across the interface and a similar rate constant was obtained when a cationic surfactant (didodecyldimethylammonium bromide) was adsorbed at the ITIES. In contrast a threefold decrease in the rate constant was observed when an anionic surfactant (dihexadecyl phosphate) was used. 

Hancock died in Budapest, Hungary, in September 1993 while on official travel. He had served as Division Director since 1990, and since 1987 had provided direction either as Acting Division Director or Deputy Division Director. He guided the development of joint programs with the Division of Chemical and Thermal Systems in Electrochemical Synthesis and in Environmentally Benign Synthesis and Processing. Hancock recognized very early the opportunities for U.S. scientists in Eastern Europe... 

Development at ElectroCell Systems AB has resulted in a multipurpose cell design that meets the specific requirements of electrochemical synthesis and environmental protection. To facilitate electrochemical scale-up of potentially promising processes four different cells have been developed and are commercially available off-the-shelf from ElectroCell Systems AB. 

Electrochemical technology has had a long association, for instance, with the pulp and paper industry through the supply of classical bleaching chemicals like sodium hydroxide, chlorine, sodium hypochlorite and sodium chlor-ate/chlorine dioxide . In this context the reader is referred to an excellent review paper by Oloman Electrochemical Synthesis and Separation Technology in the Pulp and Paper Industry [129].

Synthesis of Polysilanes. The most commonly utilized method is based on the Wurt/ type alkali metal coupling or dichlorosilanes. Other synthesis methods include dehydrogenative coupling, ring-opening polymerization, polymerization of masked disilenes. electrochemical synthesis, and polymer modification. 

W. Flitsch and G. Jones provide the first comprehensive review of pyrrolizine chemistry, an area of increasing interest. The chemistry of the arene oxides has been brought up-to-date by G. S. Shirwaiker and M. V. Bhatt. Following the overall treatment of the electrochemistry of heterocycles given by Lund in Volume 36 of this series, J. E. Toomey has now reviewed electrochemical synthesis and modification of pyridines, a subject of great industrial and academic interest. 

It should be mentioned that by changing the conditions of electrochemical synthesis — such as nature of the alcohol, the purity of the metal used as anode, the nature and concentration of the conductive additive, the voltage (usually 30 — 110 V DC is applied), the temperature, and even the construction of the cell — one can significantly effect the process of the anodic dissolution or even change its mechanism. As it has already been mentioned, the electrochemical dissolution of iron in alifatic alcohols gives insoluble iron (II) alkoxides [1005], while in 2-methoxyethanol a soluble iron (HI) complex is obtained [1514], Another example is provided by tantalum dissolution in isopropanol while high-purity metal is rapidly dissolved anodically [1639], the one containing impurities is passivated. Therefore, it is quite clear that each synthesis requires careful study, optimization of parameters of electrochemical synthesis, and isolation and purification of final products. 

A combination of different techniques can frequently improve yields of final compounds or synthetic conditions, for example a reunion of direct electrochemical synthesis and simultaneous ultrasonic treatment of the reaction system [715]. Reunion of microwave and ultrasonic treatment was an aim to construct an original microwave-ultrasound reactor suitable for organic synthesis (pyrolysis and esterification) (Fig. 3.7) [716], The US system is a cup horn type the emission of ultrasound waves occurs at the bottom of the reactor. The US probe is not in direct contact with the reactive mixture. It is placed a distance from the electromagnetic field in order to avoid interactions and short circuits. The propagation of the US waves into the reactor occurs by means of decalin introduced into the double jacket. This liquid was chosen by the authors of Ref. 716 because of its low viscosity that induces good propagation of ultrasonic waves and inertia towards microwaves. 

Chemically modified electrodes (CMEs) represent a modern approach to electrode systems. These electrodes rely on the placement of a reagent onto the surface, to impart the behavior of that reagent to the modified surface. Such deliberate alteration of electrode surfaces can thus meet the needs of many electroanalytical problems, and may form the basis for new analytical applications and different sensing devices. Such surface functionalization of electrodes with molecular reagents has other applications, including energy conversion, electrochemical synthesis, and microelectronic devices. 

The electrode material is economically important in electrochemical synthesis and an attempt is made to reduce to a minimum the use of expensive noble metals, which are regularly used in small quantities in academic investigations. Of course, the principal danger in using less stable materials is that they themselves will be oxidized or embrittled in use, respectively, as anode or cathode.

Despite the large utility of enamines in organic synthesis, the study of the electrochemistry of enamines and especially the application to synthetic organic reactions has been a rather minor area in electroorganic chemistry, and only a few studies have been reported. In this review these works are summarized and electrochemical synthesis and some reactions of a,/ -unsaturated urethanes (enecarbamates) are also described, since their chemical reactivity is considerably similar to that of the enamines.
