Herein we report new methodologies for the synthesis of the challenging ketones 2-cyanobenzophenones, based on Suzuki-Miyaura type cross-coupling reactions and very mild oxidation of 2-benzylbenzonitriles. The investigation of the reactivity of the obtained ketones highlighted a very good electrophilicity in the presence of mild carbon- and hetero-nucleophiles, allowing the synthesis of 3,3-disubstituted isoindolin-1-ones. All the developed methodologies are highly efficient and tolerate combinations of functional groups present on both the aromatic rings.

Abstract
Herein we report new methodologies for the synthesis of the challenging ketones 2-cyanobenzophenones, based on Suzuki-Miyaura type cross-coupling reactions and very mild oxidation of 2-benzylbenzonitriles. The investigation of the reactivity of the obtained ketones highlighted a very good electrophilicity in the presence of mild carbon- and hetero-nucleophiles, allowing the synthesis of 3,3-disubstituted isoindolin-1-ones. All the developed methodologies are highly efficient and tolerate combinations of functional groups present on both the aromatic rings.File in questo prodotto:
