Slow, spontaneous degradation of lansoprazole, omeprazole and pantoprazole tablets: isolation and structural characterization of the toxic antioxidants 3H-benzimidazole-2-thiones

Autor: A, Rajab, M, Touma, H, Rudler, C, Afonso, M, Seuleiman

Publikováno v: Die Pharmazie. 68(9)

The spontaneous degradation of lansoprazole, omeprazole and pantoprazole tablets upon long-term and forced storage conditions was determined by high performance liquid chromatography (HPLC). The more abundant products could be isolated by liquid chro

From the reaction of metal—carbene complexes with cyclic enol ethers to the synthesis and structure of μ-alkylidene complexes of tungsten and their possible implication in the olefin metathesis reaction

Autor: H. Rudler

Publikováno v: Journal of Molecular Catalysis. 8:53-72

Reaction of heteroatom or non-heteroatom stabilized alkylidene complexes of tungsten with cyclic enol ethers allowed us to observe products that arise from the insertion of the metal into the carbon—carbon double bond of the unsaturated starting co
