摘要
Suzuki-type coupling reactions can be performed directly in air using a catalytic system composed of iodine, potassium carbonate, and polyethylene glycol 400 (I-2/K2CO3/PEG-400). Iodine was found to be an effective additive for accelerating these couplings. The methodology is also suitable for the coupling of (E)-beta-bromostyene with phenylboronic acid, with retention of the double bond geometry.
