Abstract
The incorporation of the carbonyl moiety into organic molecules using a three-component matrix, including carbon monoxide, an organic halide, and a nucleophilic component, offers a simple and versatile approach to the formation of carboxylic acids, anhydrides, esters, amides, and ketones. The design of a sustainable synthetic protocol for aminocarbonylation can be efficiently accomplished using a multifaceted strategy that combines solid green catalysts and suitable enabling techniques. The safe and synergistic use of carbon monoxide in a microwave reactor under pressure may be able to create a technological breakthrough in aminocarbonylation reactions. Moreover, a new recyclable catalytic system "CβCAT" based on Pd(II)-triphenylphosphine embedded in cross-linked β-cyclodextrin (hexamethylene diisocyanate) has been found to be very efficient in aryl iodide aminocarbonylation reactions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
