represents one of the first examples of the addition of an organopalladium moiety to the carbon-nitrogentriplebond of a nitrile. The reaction is compatible with a number of functional groups. A reaction mechanism, as well as a model accounting for the electronic effects of substituents on the aromatic ring of the nitrile, is proposed.

Doubled up: A rhodium(III)/copper(II) system co‐catalyzes the annulation of benzimides with internal alkynes for the synthesis of indenones (see scheme; Cp*=C5Me5). The reaction involves an uncommon nucleophilic addition of a transition‐metal–carbon bond to an imide moiety. This novel reaction provides a facile route to synthesize indenones from readily available benzimides and internal alkynes.
加倍:铑(III)/铜(II)系统共催化苯并酰亚胺与内部炔烃的环化反应,以合成茚满(参见方案; Cp * = C 5 Me 5)。该反应涉及到过渡金属-碳键向酰亚胺部分的不常见亲核加成。该新颖的反应提供了从容易获得的苯甲酰亚胺和内部炔烃合成茚满的简便途径。

solvent-free synthesis of indenones from aromatic carboxylicacids and alkynes was achieved through triflic anhydride (Tf2O)-induced cyclization reaction. A variety of indenones including a bioactive PPARγ agonist were obtained in up to 90% yield at room temperature. The present protocol has the advantages of mild reaction conditions, high reaction efficiency, and feasibility of scalable synthesis, providing
Alkynes react with organoborons under a CO atmosphere in the presence of a rhodium(I) catalyst to afford mainly 5-aryl-2(5H)-furanones, α,β-unsaturated ketones, and indanones. The product selectivity can be tuned by modifying the reaction conditions.

MeOTf-induced carboannulation of arylnitriles and aromatic alkynes for synthesis of indenones under metal-free conditions has been described. When ortho-substitutedbenzonitriles were used, indeno[1,2-c]isoquinolines were formed.
