1. Homogenous catalysts
abcr offers a multitude of homogenous
which are used for C-C- and C-N coupling reactions. Many of these reactions discovered in the 1970s have meanwhile become a part of the established synthesis methods of organic chemistry. In 2010, Richard F. Heck, Ei-ichi Negishi and Akira Suzuki received the Nobel Prize for their comprehensive research in the field of catalysis.
Excellent catalysis researchers are also responsible for the Stille, Sonogashira or Kumada reaction. In the 1990s, Buchwald and Hartwig developed catalysts with sterically sophisticated
for amination. These catalysts were further developed over the last 20 years and are meanwhile available in multiple “generations”.
Replacing precious metals with cheaper and more environmentally friendly metals is regarded as a highly desirable goal in the field of catalysis. Environmental damage caused by the mining of precious metals can be minimised and process costs lowered. Several new cobalt and manganese catalysts with so-called “PN5P” triazine ligands can be used for hydrogenation and alkylation reactions and for the synthesis of heterocyclic compounds such as
abcr offers many of these products exclusively.
Hydrosilylation is regarded as the most important platinum application for homogenous catalysis. Karstedt’s catalyst “platinum divinyltetramethyldisiloxane in vinyl-terminated PDMS” as well as Speier’s catalyst hexachloroplatinic acid are available from us in various qualities.
provide the best results for metathesis reactions. These catalysts tolerate various functional groups and therefore represent a useful tool for organic synthesis.
We additionally offer a multitude of metallocene catalysts.
with various substituted cyclopentadienyl, indenyl and fluorine residues can be produced upon customer request. Their main application lies in the field of polymerisation and oligomerisation of olefins (= alkenes).
