“…Em particular, destacam os compostos homolépticos de carbonilas contendo ligação ferro-mercúrio, que têm sido estudados extensivamente [6][7][8][9][10][11][12][13][14][15][16] . Combinando-se as características dos ligantes carbonil e isocianetos, nosso grupo de pesquisa vem desenvolvendo estudos da reatividade química de derivados isocianetos do pentacarbonilferro, enfatizando-se principalmente a formação de heteronucleados com ligação metalmetal [17][18][19] . Os compostos preparados dividiram-se em adutos não iônicos [Fe(CNBu t ) n (CO) (5-n) (HgX 2 )] (n= 1, 2, 3; X= Cl, Br e I) e iônicos [Fe(CNBu t ) n (CO) (5-n) (HgX)]HgX 3 (n= 3 e 5; X= Cl, Br e I).…”

Tanto a natureza como a estabilidade relativa destes produtos depende sensivelmente do número de carbonilas substituidas por isocianetos [17][18][19] .

Recebido em 19/11/99; aceito em 15/2/01 SYNTHESIS OF THE BINUCLEAR [Fe(CNBu t)(CO) 4 (HgSO 4)] ADDUCT. The binuclear [Fe(CNBu t)(CO) 4 (HgSO 4)] adduct was obtained in the reaction of HgSO 4 with [Fe(CNBu t)(CO) 4 ] in methanol. This adduct, without a similar in the homoleptic pentacarbonyliron, was characterized by analytical and spectroscopic data. Further Mössbauer and molar conductivity studies have confirmed it's adduct nature.

Electrospray ionization mass spectrometric study of mercury complexes of N-heterocyclic carbenes derived from 1,2,4-triazolium salt precursors

By mixing 1,2,4-triazolium salts (precursors of N-heterocyclic carbenes 1-6) with mercury acetate, a number of complexes have been obtained under electrospray ionization condition. Carbenes 1 and 2 contain one carbene center; therefore, they are able to bond only one mercury cation. Carbenes 3-5 contain two carbene centers; therefore, they can bond two mercury cations. Mercury complexes of 1-5 always contain an acetate anion attached to a mercury cation. Carbene 6 also contains two carbene centers; however, its structure allows formation of a complex containing mercury bonded simultaneously to both centers, therefore, the complex that does not contain an acetate anion. The MS/MS spectra taken for complexes of carbenes 1-5 have shown formation of a cation corresponding to N1 substituent (adamantyl or benzyl), and those of complexes of carbenes 3-5 (doubly charged ions) have also shown the respective complementary partner ions. Mercury complex of 2 has yielded some other interesting fragmentation pathways, e.g. a loss of the HHgOOCCH 3 molecule. The fragmentation pathway of the mercury complexes of 6 was found to be complicated.
