Regiodivergent transition metal-catalyzed B(4)- and C(1)-selenylation reactions of o-carboranes have been demonstrated.
Reported herein is a visible-light induced selenocyclization of 2-ethynylanilines under ambient conditions, with simple FeBr3 as a dual-functional catalyst.
An efficient rhodium-catalyzed atroposelective C–H chalcogenation of biaryls with readily accessible disulfides and diselenides was developed for rapid accessing a series of axially chiral biaryl sulfides and selenides.
This review highlights the recent progress in the electrochemical difunctionalization of alkenes and alkynes involving C–S/Se bond formation to access organochalcogen frameworks.
An electrophilic domino selenylation/arylation of N-benzyl propiolamides has been developed, enabling efficient stereoselective access to α-selenyl substituted acrylamides, involving demethylenated 1,5-aryl migration.
