We present herein an unprecedented, efficient and enantioselective synthesis of triarylmethanes and 1,1‐diarylalkanes through N‐heterocyclic carbene‐catalyzed acylative desymmetrization of bisphenols. This method utilizes readilyavailable substrates, reagents and a simple procedure to deliver the valuable products in excellent enantiopurity. DFT calculations reveal that the selectivity is governed
