Possibility of Some Metals Dissolution in Mixtures of Dimethyl Sulfoxide and Aliphatic Halogen Derivative. Part III. Characteristics of the Metallic Palladium Dissolution Reaction in Binary Organic Mixtures

Jurek K., Lenarcik B.

Polish Journal of Chemistry

2006

Vol. 80, nr 5

729-736

The study of dissolution process showed that the palladium could be dissolved at 323Kin organic system which consisted of DMSO and one of the following solvents: 1,2-dibromoethane, tribromomethane, 1,1,2,2-tetrabromoethane or tetrabromomethane. As a result of the dissolution reaction in binary organic system, the square planar palladium( II) complexes were obtained. Products of the dissolution of metallic palladium were characterized using UV-Vis and IR spectroscopy, MS spectrometry, cyclic voltammetry and analytical methods.

Production of [103Pd]Bleomycin complex for targeted therapy

Due to the anticancer properties of bleomycin (BLM) complexes, production of [103Pd]bleomycin ([103Pd]BLM) was targeted. Palladium-103 (T1/2 = 16.96 d) was produced via the 103Rh(p,n)103Pd nuclear reaction using a natural rhodium target. Proton energy was 18 MeV with 200 mA irradiation for 15 h (final activity 25.9 GBq of 103Pd2+, RCP > 95%, radionuclidic purity > 99%). 103Pd was separated from the irradiated target by anion exchange using a Dowex 1´8 (Cl-)/100-200 mesh resin in the form of Pd(NH3)2Cl2 in order to react with bleomycin to yield [103Pd]BLM. Chemical purity of the final product was in accordance to the accepted limits. [103Pd]BLM was prepared with a radiochemical yield of more than 98% at 80°C in 30 min. The labeling reaction was optimized for time, temperature and ligand concentration. Radiochemical purity of more than 99% was obtained using RTLC with specific activity of about 370 MBq/mmol. The stability of the tracer was checked in the final product and presence of human serum at up to 3 h. The complex was stable in human serum at 37°C up to 2 h of incubation. Biodistribution studies using a SPECT system performed in normal rats in the first 2-3 h.

Palladium Complexes in Carbohydrate Synthesis

Zamojski A.

Polish Journal of Chemistry

2002

Vol. 76 / nr 8

1053-1084

The survey reports the results achieved in carbohydrate synthesis by application of organopalladium complexes. Most remarkable results have been noted in C-glycoside synthesis and in the chemistry of unsaturated sugars. In the majority of cases high regio- and stereoselectivity of transformations is observed. Many palladium catalysts with different organic ligands have been employed. The literature up to the end of 2001 is reviewed.
