The silver(I) salts [AgOR] (3a, R = C9H6N; 3b, R = C6H4-2-CHO, 3c, R = C6H4-2-Cl; 3d, R = C6H4-2-CN; 3e, R = C6H4-2-NO 2) are accessible by the stoichiometric reaction of [AgNO 3] (1) with HOR (2a, R = C9H6N; 2b, R = C 6H4-2-CHO; 2c, R = C6H4-2-Cl; 2d, R = C6H4-2-CN; 2e, R = C6H4-2-NO 2) in presence of NEt3. Treatment of 3a-3e with P nBu3 (4), P(OMe)3 (5a) or P(OCH 2CF3)3 (5b) in the ratios of 1:1 and 1:2, respectively, produced complexes [LmAgOR] (L = PnBu 3, m = 1: 6a, R = C9H6N; 6b, R = C 6H4-2-CHO; 6c, R = C6H4-2-Cl; 6d, R = C6H4-2-CN; 6e, R = C6H4-2-NO 2. m = 2: 7a, R = C9H4; 7b, R = C 6H4-2-CHO; 7c, R = C6H4-2-Cl; 7d, R = C6H4-2-CN; 7e, R = C6H4-2-NO 2. L = P(OMe)3, m = 1: 8a, R = C6H 4-2-CHO; 8b, R = C6H4-2-NO2. m = 2: 9, R = C6H4-2-NO2. L = P(OCH2CF 3)3, m = 1: 10, R = C6H4-2-NO 2). Based on TGA, temperature-programmed and in situ molecular beam mass spectrometry metal-organic 7e was applied as CVD precursor in the deposition of silver onto glass substrates. The resulting silver films were characterized by XRD. The SEM image of a film grown from 7e at 350 °C showed a homogeneous surface with grain sizes of 40 nm. The molecular structures of 8b and 10 in the solid state were determined. They are isostructural and are cubane-like structured. Low-temperature 31P{1H} NMR studies showed that the title complexes are dynamic in solution and exchange at room temperature their ligands.
ENZYME DETECTION/ASSAY METHOD AND SUBSTRATES

, (2008/06/13)
The invention relates to a method of detecting and/or assaying nucleoside hydrolases or nucleoside phosphorylases using a chromogenic substrate. Preferred chromogenic substrates have formula (I) where X is OH, or H, and Y is the residue of Y—OH where Y—OH is a chromophore or a compound readily converted to a chromophore and the substrates are hydrolysed by the nucleoside hydrolase to yield ribose or 2-deoxyribose plus Y—OH. Alternatively those substrates may be phosphorylysed by nucleoside phosphorylase to yield ribose-1-phosphate plus Y—OH. The methods may be used to detect and/or assay parasites in biological samples.
