Studies of General Interest

Treatment of the dimeric complexes [CpM(CO)n]2 (M = Mo, Fe, and Ni) with alkali metal salts of aromatic hydrocarbons (ArH) M+ (ArH = naphthalene, anthracene, etc.) causes reductive cleavage, affording a good preparative route  

Review articles that contain material relevant to this Chapter have appeared, dealing with electron-transfer reactions of Cp- 2Uid arene-metal complexes, electron-rich half-sandwich complexes that 

Studies of General Interest.- MO calculations have been reported for complexes of the type CpH(L) H with a view to understanding the factors responsible for the acidic or hydrldic character of the M-H bond. Redistribution reactions that Involve exchange of Cp ligands between different CpM(L) complexes have been reviewed. A variety of bimetallic y-fulvalene complexes of Cr, Mo, W, Co, and Ru, including the mixed-metal complex [(OC) Mo-Ru(CO)2(y-fulvalene)],

Studies of General Interest.- Dicationic benzene-metal complexes such as [Cp M(n-PhH) ] (M = Rh, Ir) and [ (hmb) Ru (n-PhH) ] add two hydride ions (from NaBH ) successively to give finally neutral products from which cyclohexene can be liberated by treatment with protlc acid (i.e., overall benzene + 2h + 2H - cyclohexene) j similar reactions occur with HeLl and MeONa in place of NaBH, Vanadium.- MO calculations on the triple-decker sandwich complexes... 

Studies of General Interest.- Publication of a review of thermal decomposition reactions of bis(arene) complexes of V, Cr, and Mo has been announced. 

Additional discussions are available in the General References concerning the properties of several nitrofiirans. This includes further coverage of the chemotherapeutic and physical properties antimicrobial activity bacterial resistance absorption, distribution, and excretion clinical use and safety studies, of this interesting class of antiinfective compounds. 

The study of the mechanism of cloud point micellar extractions by phases of non-ionic surfactant (NS) is an aspect often disregarded in most literature reports and, thus, is of general interest. The effective application of the micellar extraction in the analysis is connected with the principled and the least studied problem about the influence of hydrophobicity, stmcture and substrate charge on the distribution between the water and non-ionic surfactant-rich phase. 

In a first apphcation of general interest, fluorenyllithium complexes (1, Scheme 1) were studied by solid state NMR spectroscopy. One reason for the choice of this system was that the results from the X-ray investigation presented at that time and solution NMR investigations were in conflict. The bis-quinuchdine complexes investigated in the solid state by X-ray analysis show that the lithium cation is asymmetrically positioned relative to the carbon framework of the anion, mainly interacting in a fashion with carbons C-1, C-9a and C-9 (Figure 9) . 

High pressure has proven to be a useful tool in biochemistry for the study of a number of cell-mediated processes, the most important being the effect on gene expression. The pressure effect on the stability of enzymes and biopolymers is a topic of general interest that may generate a number of possible applications in the area of food science. Biochemistry and biophysics continue to attract many new research groups, especially in the field of protein chemistry. Pressure may be a tool to obtain unique textures and provide biochemical products with new properties. 

There has been little systematic or comparative study of azocines as a class, but questions of general interest include the relative stability of the eight-membered rings and bicyclic valence isomers, and the potential aromaticity of 107r-electron systems.
