The catalytic activities of the new complexes have been investigated in the coupling of arylboronic acid derivatives to various olefins. Results obtained showed interesting catalytic activities and chemoselectivities for the new complexes in the coupling reactions to produce

A series of both mono- and dinuclear gold(I) phosphinecomplexes containing monoanionic seleno- and thiosemicarbazones as ligands were prepared and fully characterized by spectroscopic methods and, in some cases, by single crystal X-ray diffraction. The in vitro anti-malaria activity of some of these compounds was investigated in chloroquine sensitive strains of Plasmodium falciparum. The IC50 results

Reactions of the RfFe(CO)4I (Rf n-C3F7 and (CF3)2CF) derivatives with chelating ditertiary phosphines give the red to brown non-ionic derivatives RfFe(CO)2I(diphos). However, reactions of the C5H5Co(CO)RfI(Rfn-C3F7 and n-C7F15) derivatives with chelating ditertiary phosphines give the yellow iodide salts [C5H5Co(diphos)Rf]I which can be converted to the corresponding hexafluorophosphate salts by

Reported are complexes of the formula Fe(dithiolate)(CO)2(diphos) and their use to prepare homo- and heterobimetallic dithiolato derivatives. The starting iron dithiolates were prepared by a one-pot reaction of FeCl2 and CO with chelating diphosphines and dithiolates, where dithiolate = S2(CH2)22– (edt2–), S2(CH2)32– (pdt2–), S2(CH2)2(C(CH3)2)2– (Me2pdt2–) and diphos = cis-C2H2(PPh2)2 (dppv), C2H4(PPh2)2
