NOVECAL has a strong expertise in calixarenes chemistry, from their synthesis to their use in various application such as catalysis, (nano)particles dispersion, carbone nanotubes synthesis, ... Particularly, we promote benzyloxycalixarenes, allowing for an easy functionalization of both the two rims, in an orthogonal way. A large range of calixarenes size (including giant calixarenes) and functionalization can be reach and are propose by NOVECAL, through the catalogue or custom synthesis.
Organometallics and catalysis
NOVECAL has a strong expertise in organometallic complexes synthesis and catalysis. We produce catalysts supported on calixarenes macrocycles. These catalysts exhibit very interesting features for the promotion of reactions such as Suzuki-Miyaura coupling, reduction or enantioselective ring-opening of epoxides:
Excellent efficiency with low catalyst amount
Easy to eliminate (filterable) with low leaching
Efficient even in concentrated media
Little impact on the process (viscosity…)
Air stable / easily handled and stored
High and reproducible metal content inside catalysts / Little waste generated
Large scope of substrates compatible
NOVECAL proposes also functionalized imidazolium salts (precursor of carbenes), enabling easy attachment on molecules, macromolecules or inorganic supports.
