Transition Metal Complexes of Diazenes, XVIII [1] Reactions of 1,2-Diazetines and 1,2-Diazetine-N-oxides with Chromium and Tungsten Carbonyls
نویسنده
چکیده
Chromium and tungsten carbonyls react with 3,3,4,4-tetramethyl-l,2-diazetine (1) or its mono-N-oxide (2) to form complexes (l)M(CO)5, (l)2M(CO)4, (l)M2(CO)io, (l)2M2(CO)8, (l)3M2(CO)6 or (2)M(CO)5 and (2)2M(CO)4, resp. In the reactions of 2 some deoxygenation affords complexes of 1 as by-products. The stability of these and other complexes of the N = N group is related to the ring size of the cyclic diazene ligand.

Bioactive Salen-type Schiff Base Transition Metal Complexes as Possible Anticancer Agents
Although metal-based anticancer drugs have been recognized as the most effective agents over the organic compounds, non-selectivity and high toxic effects have limited their applications in a way that only three Pt-analogues have progressed into clinical use. These problems have spurred chemists to develop different strategies based on alternative targets. This work focuses on predicting potenc...

The stereospecific polymerization of conjugated dienes began in 1954 with the first catalysts obtained by combining TiCl4 or TiCl3 with aluminum-alkyls, i.e. the catalytic systems previously employed for ethylene and propylene polymerizations. Subsequently, many other catalytic systems were obtained and examined by a combination of transition metal or lanthanide compounds with appropriate alkyl...
