Article Abstract
The transition-metal-catalyzed diarylation of isocyanides with triarylbismuthines was investigated in detail, and rhodium catalysts such as [RhCl(nbd)] were found to selectively afford -alkyl diaryl ketimines. On the other hand, palladium-catalyzed diarylation proceeded with the incorporation of two molecules of isocyanide, preferentially yielding ,-dialkyl or ,-diaryl -diimines. In addition, a cascade synthesis of 2,3-diarylquinoxalines starting from the palladium-catalyzed diarylation of isocyanides with triarylbismuthines was successfully achieved.

Quinolines, a significant part of nitrogen-containing heterocycles, are widely found in functional compounds. Herin, a photochemical radical cyclization reaction of -vinylaryl isocyanides and aryldiazonium tetrafluoroborates, has been reported to build 2,4-diaryl quinolines. Readily accessible aryl diazonium salts were utilized as aryl radical precursors at room temperature.

Enantioenriched chiral indoles are of high interest for the pharmaceutical and agrochemical industries. Herein, we present an asymmetric Fukuyama indole synthesis through a mild and efficient radical cascade reaction to access 2-fluoroalkylated 3-(α-cyanobenzylated) indoles by stereochemical control with a chiral copper-bisoxazoline complex using 2-vinylphenyl arylisocyanides as radical acceptors and fluoroalkyl iodides as C-radical precursors. Radical addition to the isonitrile moiety, 5-trig cyclization, and Cu-catalyzed stereoselective cyanation provide the targeted indoles with excellent enantioselectivity and good yields.

The interaction of -dilithionaphthalenes with organic cyanides was studied. Instead of the expected -diimines, the reaction leads to the formation of three types of benzo[]isoquinolines. Treatment of unsubstituted 1,8-dilithionaphthalene with aromatic nitriles results in the formation of 1-amino-1,3-diaryl-1-benzo[]isoquinolines.

Herein, cobaloxime is used for the first time as a catalyst for the synthesis of phosphorylated heteroaromatics, which is an intriguing and versatile functional motif. With visible-light irradiation, cobaloxime not only oxidizes phosphine oxides to form phosphorus radicals (P-radicals) for a subsequent reaction with radical acceptor isocyanides or heteroaromatics, but also combines the radical intermediate with β-H elimination, thereby producing phosphorylated heteroaromatics with only H or CH as byproduct. Phosphine oxides with dialkyl, alkylaryl, and diaryl substituents could be directly transformed into phosphorylated phenanthridines, benzothiazoles, isoquinolines, and common heteroaromatics.
