Convenient methods to prepare solvated rhenium oxochlorides are described; these compounds should serve as useful starting materials for rhenium chemistry. Treatment of perrhenic acid, HReO(4), with chlorotrimethylsilane or with thionyl chloride, followed by addition of tetrahydrofuran, forms the new oxochloride complexes ReO(3)Cl(THF)(2) and ReOCl(4)(THF), respectively. Small amounts of two di...

The relevance of the article does not raise any doubts, especially in context modern consumption rhenium. Rhenium is an industrial metal that has gained increasing recognition and widely used only Russia but also foreign countries, mainly form alloys with other elements, imparting special physicochemical properties to based on wolfram molybdenum. most popular addition molybdenum tungsten are re...

Rhenium-186 (tin)-labeled hydroxyethylidene diphosphonate (186Re-labeled HEDP) was evaluated in 27 men with progressive androgen-independent prostate cancer and bone metastases. Administered activities ranged from 1251 to 4336 MBq (33.8-117.2 mCi). The primary objectives were to assess tumor targeting, normal organ dosimetry, and safety. Antitumor effects were assessed by posttherapy changes in...

BACKGROUND Re(I) tricarbonyl complexes exhibit immense potential as fluorescence imaging agents. However, only a handful of rhenium complexes have been utilized in biological imaging. The present study describes the synthesis of four novel rhenium complexes, their characterization and preliminary biological studies to assess their potential as biological imaging agents. RESULTS Four facial rh...

The novel antitumor system including cluster rhenium compounds and cisplatin (Re-Pt 4:1 system) has been recently presented [Anticancer Research, 2007]. The structural types of dirhenium(III) carboxylates with formulas Re2(RCOO)4Cl2, Re2(RCOO)3Cl3, cis-Re2(RCOO)2Cl4, trans-Re2(RCOO)2Cl4, Re2(HPO4)4Cl2, phosphates and mixed carboxylates – phosphates were the matter of concern. The binuclear clus...

the possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. the results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. on the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...

The aim of this study was to determine whether shorter-lived radionuclides can reduce red marrow (RM) toxicity for i.p. radioimmunotherapy (RIT). The potential radionuclides, which included Lu-177, I-131, Y-90, Re-186, Re-188, and Ho-166, were attached to antibody CC49. Each radiopharmaceutical was assumed to have identical in vivo pharmacokinetics. Blood and whole body retention data acquired ...

Salt metathesis reactions between a low-valent rhenium(i) complex and series of amidinate-supported tetrylenes led to rhenium metallotetrylenes with varying extents Re–E multiple bonding.
