Bis(dialkylaminomethyl)-phenylenedipalladium (II) compounds

Abstract

Abstract Certain bis(di-lower-alkylaminomethyl)phenylenedipalladium(II) halides (I), e.g., 3,6-bis(diethylaminomethyl)-1,2phenylenedipalladium(II) dichloride and the corresponding 2,5-, 1,4- isomer, are prepared by reacting a complex inorganic palladium halide with a bis(dialkylaminio)xylene, e.g., sodium palladium chloride with Alpha , Alpha ''-bis(diethylamino)-pxylene. Compounds I can be converted to novel chelates (II), e.g., 2,5-bis(diethylaminomethyl)-1,4-phenylenedipalladium(II) bis(2,4-pentanedionate), or salts (III), e.g., 3,6bis(diethylaminomethyl)-1,2-phenylenebis(pyridinepalladium(II)) Mu -chloride hexafluorophosphate, by reaction with a chelating agent, e.g., 2,4-pentanedione, or a cyclic amine, e.g., pyridine. The compounds are useful as components of precious-metal decorating compositions and as catalysts for polymerizing acetylene.
