Isatin and related derivatives are synthetically versatile substrates. These compounds can
form a wide range of heterocyclic structures. These characteristics make isatin and its …

An atom-economical hydrosulfonation of densely functionalized alkenes under catalyst-free
conditions is described. Alkenes possessing a hydroxy-oxindole moiety underwent …

An electricity promoted chemoselective functionalization of alkenes having oxindole moiety
with thiols and selenols under the catalyst‐free conditions to afford thioethers and …

A metal-free direct C–H selenation of aniline derivatives via an iodine-catalyzed C–Se bond
formation using diselenides as a selenium source at ambient temperature is described. A …

In this study, a substrate-controlled dual functionalization of alkenes under catalyst-free and
solvent-free conditions is described. Alkenes possessing different electron-withdrawing …
