Fluorous tagging of 1,4-diazabicyclo[2.2.2]octane (DABCO) through the halogen bond creates a recyclable organocatalyst for the Morita-Baylis-Hillman reaction, say scientists in France.
Fluorous tagging of DABCO through halogen bonding makes recyclable catalyst for well known organic reaction
Julien Legros and colleagues from the University of Paris-Sud, applied the fluorous tagging technique (often used in organometallic catalysis) to an organocatalyst, where the fluorous tags were ‘grafted’ in a supramolecular fashion through the halogen bond. The resulting catalyst is readily accessible and can be recovered using a simple precipitation and filtration method, allowing recyclability up to five times.
