RESUMEN
Commercially available hydroxypropyl methylcellulose capsules are employed as a fast, safe, and user-friendly chemical delivery system containing all reagents (catalyst, ligand, and base) for three important transition-metal-catalyzed reactions: Buchwald-Hartwig, Suzuki-Miyaura, and metallophotoredox C-N cross-coupling reactions. This encapsulation methodology simplifies the screening of reaction conditions and the preparation of compound libraries using parallel synthesis in organic solvents or aqueous media. These reagents-containing HPMC capsules are easy to prepare, come in different sizes, and can be stored on the bench under noninert conditions.
