Pauling Electronegativity

The class structure of transition metals chemisorbing carbon monoxide was determined by expressing the following fundamental parameters in the form of functions: The molar heat capacity, the 1st and 2nd ionization energy, the heat of fusion, Pauling electronegativity, the electric conductivity, Debye temperature, the atomic volume of metal. Adsorption heats have been predicted for twelve transition metals.

Dicobalt Octacarbonyl

Cocyclization of alkynes, alkenes, and carbon monoxide by transition metals (known as Pauson­Khand reaction when dicobalt octacarbonyl complexes are used) has been accepted as one of the most powerful tools in the synthesis of cyclopentenones. Despite significant progress in the various aspects of the reaction, we still needed new catalysts to expand the scope of the reaction further. We found rhodium (I) catalysts, e.g., RhCl(PPh3)3, trans-RhCl(CO)(PPh3)2, RhCl-(CO)(dppe), and trans-[RhCl(CO)(dppp)]2, were also effective for this transformation. The scope and the efficiencies of the reaction could be tuned and expanded by the choice of catalysts. For example, we were able to devise an enantioselective PK-type reaction and a tandem strategy employing two catalysts in one pot. These results will be presented.

Compounds of the general formulae M(CO)3(dpe)X2, [M(CO)2(dpe)1.5X2]2, and M(CO)2(dpe)2X2 have been prepared and characterized (M = Mo, W; dpe = bis- (1,2-diphenylphosphino)ethane; X = Cl, Br, I). All of the compounds are diamagnetic and most of them are non-electrolytes. However, conductivity measurements indicate that, for the iodo derivatives only, the bis(dpe) compounds should be formulated as 1 : 1 electrolytes, [M(CO)2(dpe)2I]I. ��� For the iodo series of compounds only, there is a complex series of reversible reactions including a new type of carbon monoxide carrying system. In addition, the dimeric dpe derivatives are cleaved by carbon monoxide at room temperature and pressure to give equal quantities of [M(CO)2(dpe)2I]I and M(CO)3(dpe)I2.
