This work reports the carbonylative Suzuki–Miyaura coupling of aryl iodides catalyzed by palladacycles. More importantly, the palladacycles have been used to generate high turnover numbers (TON’s) and turnover frequencies (TOF’s). A range of aryl iodides can be coupled with arylboronic acids, generating TON’s in the range of 106 to 107 and TOF’s in the range of 105 to 106 h–1. Comparison of the palladacycles with a conventional palladium source shows their superiority in generating high TON’s and TOF’s.
