Reagent capsules can help to resolve the compatibility problem of reagents in multicomponent processes. Herein we demonstrate a facile method for encapsulating smelly liquid chemicals and its application in a modular palladium‐catalyzed carbonylative synthesis of multi‐substituted thiophenes from terminal alkynes and aryl iodides as well as a palladium‐catalyzed carbonylative synthesis of benzothiophene

An interesting domino reaction for the synthesis of substituted naphthyl ketones has been developed using readily accessible starting materials. This domino reaction proceeds via in situ incorporation of an acetal followed by intramolecular heteroalkyne metathesis/annulation in an ortho-alkynylacetophenone derivative. A deuterium incorporation experiment has been carried out to understand the mechanism
