Direct Hydrodecarboxylation of Aliphatic Carboxylic Acids: Metal- and Light-Free

A mild and inexpensive method for direct hydrodecarboxylation of aliphatic carboxylic acids has been developed. The reaction does not require metals, light, or catalysts, rendering the protocol operationally simple, easy to scale, and more sustainable. Crucially, no additional H atom source is required in most cases, while a broad substrate scope and functional group tolerance are observed.

Synthesis method of aryl tertiary sulfonamide compounds promoted by visible light

The invention provides a synthesis method of aryl tertiary sulfonamide compounds promoted by visible light. In a non-protonic solvent, N-benzyl tertiary amine and arylsulfonyl chloride are used as rawmaterials, under the conditions of photosensitizer catalysis and illumination, a reaction is carried out for 1-4h at room temperature, and then separation and purification are carried out to obtain the product. The synthesis method of the aryl tertiary sulfonamide compound provided by the invention has the advantages of mild reaction conditions, simplicity and convenience in operation, short reaction time, no need of any transition metal catalysis and environmental friendliness.

Olefination via Cu-Mediated Dehydroacylation of Unstrained Ketones

The dehydroacylation of ketones to olefins is realized under mild conditions, which exhibits a unique reaction pathway involving aromatization-driven C-C cleavage to remove the acyl moiety, followed by Cu-mediated oxidative elimination to form an alkene between the α and β carbons. The newly adopted N′-methylpicolinohydrazonamide (MPHA) reagent is key to enable efficient cleavage of ketone C-C bonds at room temperature. Diverse alkyl- and aryl-substituted olefins, dienes, and special alkenes are generated with broad functional group tolerance. Strategic applications of this method are also demonstrated.
