Comprehensive Summary Catalytic four‐component radical carbonylation of unactivated alkenes has recently been recognized as a robust protocol for rapid construction various structurally diverse carbonyl compounds. Given the significance fluorine‐containing groups, this reaction class extensively applied to assembly variety perfluoroalkyl carboxylic acid derivatives by transition metal catalysis. Herein, we report visible‐light‐driven relay 1,2‐perfluoroalkylation aminocarbonylation using CO gas source and 4CzIPN organic photocatalyst. A wide range amines were well tolerated, providing valuable β‐perfluoroalkylated amides with generally good yields high chemoselectivity.

Abstract A Pd‐catalyzed three‐component intermolecular reaction between aryl halides, ClCF 2 COONa and phenols is developed. series of benzoates were synthesized in up to 84 % yield via difluorocarbene transfer carbonylation. It devoted acquiring the targeted products by construction new C−C, C=O C−O bonds a one‐pot, one‐step process. The feature this method includes use readily available starting materials, showing outstanding resistance spatial obstruction simple operation procedure with mild conditions. Therefore, makes methodology useful alternative other schemes typically used for synthesis esters.

A new strategy to obtain β,γ-unsaturated ketones via the cross-coupling of 1,3-butadiene, alkyl bromides, and arylboronic acids under 1 bar CO with nickel as catalyst has been developed. This newly developed four-component carbonylation procedure features advantages including using a cheap catalytic system, high step economy, mild reaction conditions, excellent 1,4-regioselectivity, thereby providing sustainable alternative tool for production compared present tactics. To elucidate application potential this method, olefin synthons are derived from representative coupling product.

A nickel-catalyzed acylation of vinylpyridines with CO at atmospheric pressure is reported, allowing for an expedient approach to synthesize β-acyl pyridine derivatives high regio- and chemoselectivity. The electron-withdrawing property plays pivotal roles in activating the alkenyl group, thereby facilitating this carbonylative process. In addition vinylpyridines, other alkenylheterocycles such as thiazole quinoline were also suitable method.

Here we present an effective nickel-catalyzed carbonylative cross-coupling for direct access to alkyl aryl ketones from readily accessible redox-activated tetrachlorophthalimide esters and boronic acids. The methodology, which is run employing only 2.5 equivalents of CO simple Ni(II) salts as the metal source, exhibits a broad substrate scope under mild conditions. Furthermore, this carbonylation chemistry provides easy switch between isotopologues stable (

An efficient organophosphorus-catalyzed thiocarbonylation reaction of disulfides with carboxylic acids under air conditions was described. Various functional groups on and can be tolerated the present conditions, affording thioesters in good to excellent yields. This method exhibited chemoselectivity applied for late-stage functionalization drug molecules containing a acid group.
