A violet-light-induced ring-opening of anthranils with chlorodiazirines has been developed. The metal-free protocol provides a rapid and efficient approach to N-(2-carbonylaryl)benzamides in moderate good yields under mild conditions. reaction appears involve α-chlorocarbenes, which trigger the anthranils.

The hybrid nature of Pd(I)-alkyl radical species has enabled a wide array radical-based transformations. However, in this transformation, the secondary are prone to recombining into Pd(II)-alkyl give Heck-type products via β-H loss. Herein, we report visible-light-induced, three-component Pd-catalyzed 1,2-aminoalkylation alkenes with readily available alkyl halides and amines construct C–C C–N bonds simultaneously. Mechanistic investigation shows that intermediate o-quinone methide produced is key factor transformation.

Abstract A straightforward and efficient electrochemical method for the anodic oxidative selenenylation of 2-(2-arylallyl)phenols a 2-(3-arylbut-3-en-1-yl)phenol with diselenides under ambient air conditions has been outlined. This allows synthesis selenyl-dihydrobenzofurans chromane featuring sterically hindered tetrasubstituted carbon center, demonstrated through 25 examples yields reaching up to 98%. Initial mechanistic investigations suggest likely participation pivotal seleniranium cation species in regulating reactivity.
