Active polymerization catalysts, novel resin-bound diimine complexes of nickel(II) and palladium(II) are obtained by combinatorial synthesis and combined in a catalyst library. By tagging with fluorescent markers, the catalysts can be coded. Therefore, after cleavage of the tag from the polymer-coated resin, HPLC can be used to determine the pathway along which the products were formed.
Aktive Polymerisationskatalysatoren sind die neuartigen, harzgebundenen Bisiminnickel(II)‐ und ‐palladium(II)‐Komplexe, die durch kombinatorische Synthesen erhalten und zu einer Katalysatorbibliothek zusammengestellt wurden. Durch Einfügen von Fluoreszenzmarkern lassen sich die Katalysatoren kodieren, so daß nach dem Abspalten der Marker vom polymerbeschichteten Harz HPL‐chromatographisch zurückverfolgt werden kann, nach welchem Syntheseverlauf die Produkte entstanden sind.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
