The reaction of 2 with or in tetrahydrofuran gives the mixed manganese-gold clusters 3-H)(μ-AuPR3)> (R = Ph (1) or Me (2)) and 23-H)Au>2(μ-diphos)> (diphos = dppe (3) or dppm (4)).The reaction between the same manganese anion and produces 3-H)Au>3(triphos)>3- (5), 3-H)Au>2(triphos)(AuCl)>2- (6) or 3-H)Au>(triphos)(AuCl)2>- (7), depending on the molar ratio of the reagents.Isoelectronic iron-goldcomplexes (3-x)(triphos)(AuCl)x>(3-x)- (x = 0 (8), 1 (9) or 2 (10) were obtained by the reaction of the trinuclear 2- anion with in the appropriate molar ratio.Attempts to obtain mixed manganese-iron-gold clusters resulted in a mixture of compounds, the nature of which has been explained in terms of metal-ligand redistribution processes.Keywords: Gold; Manganese; Iron; Metal-metal bonds; Clusters; Electrophilic addition

Paragraph 0055; 0056; 0057; 0058; 0059; 0060, (2016/12/16)
The invention discloses a method for preparing an organic phosphonic gold chloride (I) compound. The method comprises the following steps: (1) adding chloroauric acid hydrated salt into a reaction container, dissolving with water, and uniformly stirring in an ice-water bath; (2) keeping the temperature of the ice water in the reaction container, dripping a glucosinolates diaryl compound or a derivative of the glucosinolates diaryl compound, and stirring uniformly; (3) dripping a mixed liquid of phosphine-containing ligand and ethanol into the reaction container one droplet by one droplet, removing the ice-water bath, recovering the room temperature naturally, and stirring for 2-5 hours; (4) stopping stirring, performing suction filtration, washing with cold methanol, dissolving the collected solid with an organic solvent, and performing suction filtration again so as to remove insoluble matters; (5) performing concentration spinning drying on the solution, recrystallizing with a solvent, and performing suction filtration again, thereby obtaining the organic phosphonic gold chloride (I) compound. As the glucosinolates diaryl compound or the derivative of the glucosinolates diaryl compound is taken as a reduction reagent, and due to reaction between the chloroauric acid hydrated salt and the phosphine-containing ligand in an ethanol-water system, environment-friendly, safe and efficient production of the organic phosphonic gold chloride (I) compound can be achieved, and moreover, industrial application of the organic phosphonic gold chloride (I) compound is facilitated.
Synthesis, structures and anti-malaria activity of some gold(i) phosphine complexes containing seleno- and thiosemicarbazonato ligands

A series of both mono- and dinuclear gold(i) phosphine complexes 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 show that the sulfur containing compounds exhibit activity similar to that of chloroquine, whilst the selenium derivatives display only moderate anti-malaria activity.
