O estudo de [Fe(CO)5], [Fe2(CO)9] e [Fe3(CO)12] como precursores catalíticos nas reações de hidrogenação do ciclohexeno e 1-hexeno foi efetuado. Um reator fotoquímico com fluxo de H2 e irradiação UV-vis foi usado no processo. Os espectros infravermelho das amostras mostraram a formação de [Fe(CO)4(olefina)] e [HFe(CO)3(π-alila)] como intermediários. A atividade mostrada do [Fe2(CO)9] na hidroge...

In many previous studies, nonaqueous synthesis of Pt nanocubes with tunable size has been achieved by the use of metal carbonyls (e.g., Fe(CO)(5), Co(2)(CO)(8), W(CO)(6)). The presence of zero-valent metals in the carbonyls was demonstrated as the key factor to the nanocube formation but the role of CO was entirely ignored. By using CO alone, we have now demonstrated that the favorable growth o...

Protein oxidationM.longissimus dorsi andM. semimembranosuswas studied in ram lambs of Northeastern Bulgarian Fine Wool Breed and cross of this breed with Ile de France, reared and in doors and on pasture.The degree of protein oxidation is determined by measuring the content of carbonyls, formed during the storage of the investigated muscles at low temperatures(4˚С till6thday and -20˚С till90thd...

Effective methodologies for efficient preparation of semicarbazones from aldehydes or ketones via milling and the subsequent regeneration of the parent carbonyls by gaseous nitrogen dioxide are described under solid-solid and gas-solid reaction conditions, respectively. These methods are fast, simple and environmentally benign which do not require the use of any auxiliaries such as catalyst...
