palladium‐NHC‐catalyzed (NHC=N‐heterocyclic carbene) Suzuki‐Miyaura cross‐coupling of amides and esters via highly chemoselective N−C(O) and O−C(O) cleavage with aryl boronic acids using green, sustainable and eco‐friendly 2‐methyltetrahydrofuran (2‐MeTHF) is reported. A variety of amides and aryl esters were coupled with aryl boronic acids in high to excellent yields. This method employs commercially‐available
