SYNTHESIS AND PROPERTIES OF TRANSiTION METAL TO CARBON BONDS
نویسنده
چکیده
The known properties of alkyl and aryl derivatives of transition elements are reviewed, with particular attention to binary compounds of this type. Factors contributing to thermal stability of metal—carbon a-bonds are discussed and new contributions are presented dealing with: (1) chemistry of titanium(Iv) and titaniurn(n); (ii) metal—carbon bonds in N,N'-ethylenebis(salicylideneiminato) complexes of iron and cobalt; (iii) reactivity of rhenium(I) bromo-carbonyl complexes; (iv) use of metal carbonyls as a source of zerovalent metals in the preparations of binary complexes of 9,10-phenanthrenequinone and (v) synthesis of cyclopentadienyl-alkyl and cyclopentadienyl-aryl derivatives of uranium(rv).

Metal-catalyzed carbon-sulfur bond formation.
In organic synthetic reactions, the scope and application of organosulfur chemistry have increased tremendously since sulfur-containing groups serve an important auxiliary function in synthetic sequences.1 Illustrative examples are the reversal of polarity (Umpolung), the enhancement of the acidity of C-H bonds, and the transfer of chirality from sulfur to carbon.2 On the other hand, transition...
