Abstract
Official abstract text for this publication.
Platinum complex of the type [L1L2Pt[O(CO)R1]X] n , wherein L1 and L2 are the same or different monoolefin ligands or together represent a compound L1L2 acting as a diolefin ligand, wherein X is selected from bromide, chloride, iodide, and —O(CO)R2, wherein —O(CO)R1 and —O(CO)R2 are the same or different C6-C18 or C8-C18 non-aromatic monocarboxylic acid groups with the exception of a phenylacetic acid group, or together represent a C8-C18 non-aromatic dicarboxylic acid group —O(CO)R1R2(CO)O—, wherein it is a mononuclear platinum complex where n=1, or wherein, in the event of the presence of L1L2 and/or of —O(CO)R1R2(CO)O—, it may be a polynuclear platinum complex with a whole number n>1.
First claim
Opening claim text (preview).
The invention claimed is: 1. A platinum complex of the formula [(NBD)Pt[O(CO)R1] 2 ] n , wherein n is 1 or 2, and R1 is a C 5 -C 17 non-aromatic hydrocarbon group. 2. A method for producing a platinum complex according to claim 1 , the method comprising emulsifying a two-phase system, wherein one phase comprises an at least substantially water-immiscible organic solution of a reactant of the formula [(NBD)PtX 2 ] n , wherein X is selected from bromide, chloride, and iodide; and the other phase comprises an aqueous solution of an alkali and/or magnesium salt of a monocarboxylic acid of the formula R1COOH, wherein R1 is a C 5 -C 17 non-aromatic hydrocarbon group. 3. The platinum complex of claim 1 , wherein the platinum complex is: (NBD)Pt[O(CO)CH(C 2 H 5 )C 4 H 9 ] 2 . 4. The platinum complex of claim 1 , wherein R1 is a C 7 -C 17 non-aromatic hydrocarbon group.
